Package
mosdef 1.1.0
1 Introduction
This vignette describes how to use the mosdef package for performing tasks commonly associated to your Differential Expression workflows.
This includes functionality for
plotting your expression values and differential expression results, both individually and as summary overviews (
gene_plot,de_volcano,go_volcano,plot_ma,get_expr_values)running different methods for functional enrichment analysis, providing a unified API that simplifies the calls to the individual methods, ensuring the results are also provided in a standardized format (
run_cluPro,run_topGO,run_goseq)decorating and improving your analysis reports (assuming these are generated as Rmarkdown documents). This can enhance the experience of browsing the results by automatical linking to external databases (ENSEMBL, GTEX, HPA, NCBI, … via
create_link_functions, wrapped into abuttonifierto seamlessly multiply the information in a simple tabular representation). Additional info on frequently used features such as genes and Gene Ontology terms can also be embedded withgeneinfo_to_htmlandgo_to_html
The mosdef package as a whole aims to collect the MOSt frequently used DE-related Functions, and is open to further contributions from the community.
All in all, the objective for mosdef is to streamline the generation of comprehensive, information-rich analysis reports.
Historically, many of these functions (at least conceptually) have been developed in some of our other Bioconductor packages, such as pcaExplorer, ideal and GeneTonic. mosdef is the attempt to achieve a better modularization for the most common tasks in the DE workflow.
1.1 Required input
In order to use mosdef in your workflow, two main inputs are required:
de_container, a dataset containing the expression matrix for example aDESeqDataSetres_de, a dataset, such as aDESeqResultsstoring the results of the differential expression analysis
Additionally, the mapping parameters, shared by a number of functions, refers to the annotation of your species provided by AnnotationDbi-like packages, which are commonplace in the Bioconductor environment.
For human, this would be org.Hs.eg.db, and for mouse org.Mm.eg.db.
Currently, mosdef is able to feed on the classes used throughout the DESeq2 approach, but can easily be extended for the corresponding implementations in edgeR and limma.
1.2 Demonstrating mosdef on the macrophage data
In the remainder of this vignette, we will illustrate the main features of mosdef on a publicly available dataset from Alasoo et al., “Shared genetic effects on chromatin and gene expression indicate a role for enhancer priming in immune response”, published in Nature Genetics, January 2018 (Alasoo et al. 2018) doi:10.1038/s41588-018-0046-7.
The data is made available via the macrophage Bioconductor package, which contains the files output from the Salmon quantification (version 0.12.0, with Gencode v29 reference), as well as the values summarized at the gene level, which we will use to exemplify the analysis steps.
In the macrophage experimental setting, the samples are available from 6 different donors, in 4 different conditions (naive, treated with Interferon gamma, with SL1344, or with a combination of Interferon gamma and SL1344).
For simplicity, we will restrict our attention on the comparison between Interferon gamma treated samples vs naive samples.
2 Installation
To install mosdef, you can run the following commands:
if (!require("BiocManager")) {
install.packages("BiocManager")
}
BiocManager::install("mosdef")If you want to install the development version from GitHub, you can alternatively run this command:
BiocManager::install("imbeimainz/mosdef")3 Getting started
Once installed, the mosdef package can be loaded and attached to your current workspace as follows:
library("mosdef")
#> 4 Load the data
We will use the well known macrophage data as an example.
Notably, we correctly specify the experimental design as ~ line + condition, to obtain the effect due to the condition, while accounting for the cell line.
If you are familiar with the DE workflow, you can skim over this section and read more on the functionality of mosdef in Section 5.
suppressPackageStartupMessages({
library("macrophage")
library("DESeq2")
library("org.Hs.eg.db")
})

dds_macrophage <- DESeqDataSet(gse, design = ~ line + condition)
#> using counts and average transcript lengths from tximetarownames(dds_macrophage) <- substr(rownames(dds_macrophage), 1, 15)We perform some filtering on the features to be kept, and define the set of differentially expressed genes contrasting the IFNg and the naive samples.
Notably, we correctly specify the lfcThreshold parameter instead of a post-hoc approach to filter the DE table based on the log2 fold change values - see https://support.bioconductor.org/p/101504/ for an excellent explanation on why to prefer the more rigorous (yet, likely conservative) method defined in the chunk below.
keep <- rowSums(counts(dds_macrophage) >= 10) >= 6

lfcThreshold = 1,
alpha = 0.05)Please refer to the vignette of the DESeq2 or edgeR packages for more complex experimental designs and/or additional options in each workflow.
The aim for this section was simply to generate exemplary objects to work with and provide to the mosdef functions.
5 Generating enrichment results with a unified API
mosdef allows you to create your enrichment results right from your DESeqDataset and DESeqResults objects using 3 possible algorithms, widely used:
For more information on the differences between these algorithms we refer to their individual vignettes and publications.
All of these algorithms require an annotation to function properly, so make sure you have installed and use the correct one for your experimental data.
The default is org.Mm.eg.db (Mus musculus). The macrophage data however stems from human, so we need org.Hs.eg.db, and we load this package in the following chunk:
library("AnnotationDbi")
library("org.Hs.eg.db")We also want to add a symbol column for later use - and, in order to add a human readable name for our features of interest:
res_macrophage_IFNg_vs_naive$symbol <-
AnnotationDbi::mapIds(org.Hs.eg.db,
keys = row.names(res_macrophage_IFNg_vs_naive),
column = "SYMBOL",
keytype = "ENSEMBL",
multiVals = "first"
)
#> 'select()' returned 1:many mapping between keys and columnsWe indeed recommend to use identifiers as row names that are machine-readable and stable over time, such as ENSEMBL or GENCODE.
To ensure that we are using objects that would work out-of-the-box into mosdef, we provide some utilities to check that in advance - this can relax the need of specifying a number of parameters in the other functions.

mosdef_res_check(res_macrophage_IFNg_vs_naive)5.1 mosdef and topGO
topGO is a widely used option to obtain a set of spot-on Gene Ontology terms, removing some of the more generic ones and therefore also reducing the redundancy which is inherent in the GO database (Ashburner et al. 2000).

#> We suggest further subsetting the output list by for example:
#> using a pvalue cutoff in the column:
#> 'p.value_elim'.The run_topGO function will return a table with the analysis for all possible GO terms (currently when using the “BP” ontology on the macrophage dataset that is 6116 terms).
Not all of these results are significant, and this list can (should) be further subset/filtered. For example by using a p-value cutoff.
The key parameters for run_topGO() are defined as follows:
de_container: YourDESeqDatasetobjectres_de: YourDESeqResultsobjectontology: Which gene ontology to analyse, default is “BP”mapping: The annotation/speciesgene_id: Which format the genes are provided. If you provide aDESeqDatasetandDESeqResults, then mosdef does it for you and uses symbols. If you provide vectors please specify a value.FDR_threshold: The pvalue to use to count a gene as significant. The default is 0.05 but if you want a stricter analysis you could set this to 0.01 for examplede_type: Which genes to analyse. The default is all (“up_and_down”) Other possibilities are only up-/down-regulated (“up”/“down”) genes.add_gene_to_terms: Logical, whether to add a column with all genes annotated to each GO term.topGO_method2: Character, specifying which of the methods implemented bytopGOis to be used. The default is elim. For more info look at the documentation of topGO.min_counts: Minimum number of counts a gene has to have to be considered for the background. The default is 0 and we advise this parameter is only used by expert users that understand the impact of selecting “non-standard” backgrounds.top_de: The number of genes to be considered in the enrich analysis. The default is all genes, this can be reduced to reduce redundancy. In this case, we take the top 700 highest DE genes based of padj score. If this number is bigger than the total amount of de genes the parameter defaults back to all genes.verbose: Whether or not to summarise the analysis in a message.

5.2 mosdef and goseq
The method implemented in the goseq package is able to handle the selection bias inherent in assays such as RNA-seq, whereas highly expressed genes have a higher probability of being detected as differentially expressed.
Parameters like top_de, min_counts, verbose, FDR_threshold and de_type can also be used here (for more detail on these parameters see above), as they are a part of the shared API with run_topGO and run_cluPro.
Importantly, the feature length retrieval is based on the goseq() function, and this requires that the corresponding TxDb packages are installed and available. So make sure one is installed on your machine. For human samples, the recommended one is TxDb.Hsapiens.UCSC.hg38.knownGene.

5.3 mosdef and clusterProfiler
Parameters like top_de, min_counts, verbose, FDR_threshold and de_type
can also be used here (For more detail on these parameters see above).
If you want to further customize the call of enrichGO() inside the function, have a look at the documentation for enrichGO() from clusterProfiler Those parameters can be added to the run_cluPro() function call within the ellipsis (...).
For example, as we are doing in the chunk that follows, we set Biological Process as the ontology to be used, by specifying ont = "BP"
clupro_macrophage <- run_cluPro(
de_container = dds_macrophage,
res_de = res_macrophage_IFNg_vs_naive,
mapping = "org.Hs.eg.db",
keyType = "SYMBOL",
ont = "BP"
)
head(clupro_macrophage)Importantly, keyType is relevant for the enrichGO() function that is wrapped in this routine.
If using DESeqDataset and DESeqResults, this has to be “SYMBOL” which is also the default.
If you use vectors please specify here what type of IDs you provide.
Again, to save time when rendering the vignette, we load the objects provided alongside this package to demonstrate the output (see also this script included in the package to inspect the code used to generate the objects):
data(res_enrich_macrophage_cluPro, package = "mosdef")The function will return a large enrich result containing some metadata and the enrichment results with 9 columns.

5.4 Alternative ways to run enrichment analyses, within mosdef
All of these functions tailored to run enrichment methods also work if you only have/provide a vector of differentially expressed genes and a vector of background genes.
Most of the above mentioned parameters work here as well (top_de, verbose), however parameters like min_counts and de_type will not affect the result, since they need further information which can only be found in the DESeqDataset and DESeqResults (in this case, access to the counts from the DESeqDataset object de_container and the Log2FoldChange from the DESeqResults object passed to res_de).

mosdef provides some wrappers to commonly used visualizations of individual genes, as well as summary visualizations for all features at once.
6.1 Individual genes - gene_plot()
An elegant way to plot the expression values (by default the normalized counts) of a certain gene of interest, split up by a covariate of interest - for example, the condition, IFNg vs naive.
gene_plot(
de_container = dds_macrophage,
gene = "ENSG00000125347",
intgroup = "condition"
)
Key parameters are in this case:
de_container: YourDESeqDatasetgene: The gene of interestintgroup: A character vector of names incolData(de_container)used for grouping the expression values.
Notably, gene_plot() also has some heuristics to suggest an appropriate layer of plotting the data points, depending on the number of samples included in each individual group - this include the simple jittered points, a boxplot, a violin plot, or a sina plot.
This automatic behavior can be suppressed by specifying a different value for the plot_type parameter.
6.2 All genes at once - Volcano plots
Volcano plots are one of the most well known and used plots to display differentially expressed genes.
These functions return a basic ggplot object including the most important parts when creating a volcano plot.
volcPlot <- de_volcano(
res_de = res_macrophage_IFNg_vs_naive,
mapping = "org.Hs.eg.db",
logfc_cutoff = 1,
FDR = 0.05,
labeled_genes = 25
)
#> 'select()' returned 1:many mapping between keys and columnsvolcPlot
#> Warning: Removed 17782 rows containing missing values or values outside the scale range
#> (`geom_text_repel()`).
Again, an overview on the key parameters:
res_de: YourDESeqResultsmapping: The annotation/species: Important to generate symbols for labeling.labeled_genes: The number of the top DE genes to be labeled. Default is 30.logfc_cutoffandFDR: Where to draw the lines in the plot and which genes to mark as significant. The default is 1 (meaning L2FC +/-1): So genes with a FoldChange higher than 1 or lower -1 and a padj value below 0.05.
This plot can be later modified by the user, like any regular ggplot object. For example:
library("ggplot2")
volcPlot +
ggtitle("macrophage Volcano") +
ylab("-log10 PValue") +
xlab("Log 2 FoldChange (Cutoff 1/-1)")
#> Warning: Removed 17782 rows containing missing values or values outside the scale range
#> (`geom_text_repel()`).
For further possibilities please look at the ggplot2 documentation.
In addition to only focusing on differentially expressed genes, in a volcano plot the user can also highlight genes associated with a certain GO term of interest.
This can be done with the go_volcano() function:
Volc_GO <- go_volcano(
res_de = res_macrophage_IFNg_vs_naive,
res_enrich = res_enrich_macrophage_topGO,
term_index = 1,
logfc_cutoff = 1,
FDR = 0.05,
mapping = "org.Hs.eg.db",
n_overlaps = 50,
col_to_use = "symbol",
enrich_col = "genes",
down_col = "black",
up_col = "black",
highlight_col = "tomato"
)
Volc_GO
#> Warning: Removed 17719 rows containing missing values or values outside the scale range
#> (`geom_label_repel()`).
#> Warning: ggrepel: 22 unlabeled data points (too many overlaps). Consider
#> increasing max.overlaps
The key parameters:
res_de: YourDESeqResultsres_enrich: Your enrichment resultsterm_index: The index(row) where your term of interest is located in your enrichment result.logfc_cutoffandFDR: Where to draw the lines in the plot and which genes to mark as significant. The default is one (meaning L2FC +/-1): So genes with a FoldChange higher than 1 or lower -1 and a padj value below 0.05.mapping: The annotation/species: Important to generate symbols for labeling.n_overlaps: The number of overlapsggrepelis supposed to allow for labeling (increases number of labeled genes).col_to_use: Name of the column in your res_de containing the gene symbols.enrich_col: Name of the column in your res_enrich containing the gene symbols. For an example seerun_topGOdata provided in mosdef:data(res_enrich_macrophage_topGO, package = "mosdef").down_col: Colour for your downregulated genes (genes with alogfc_cutoffbelow the value specified).up_col: Colour for your upregulated genes (genes with alogfc_cutoffabove the value specified).highlight_col: Colour for your genes associated with the given term of interest.
6.3 All genes at once - MA plots
An alternative to the volcano plot, less focused on the individual significance values and more focused on the combination of mean expression and changes in expression levels, is the MA plot. It can be considered an extension of the Bland-Altman plot for genomics data. This grants an overview of the differentially expressed genes across the different levels of expression.
plot_ma() also allows you to set x and y labels right away, but we provide some default values.
However, similar to de_volcano(), these can also be set later on by directly modifying the returned ggplot object.
maplot <- plot_ma(
res_de = res_macrophage_IFNg_vs_naive,
FDR = 0.05,
hlines = 1
)
# For further parameters please check the function documentation
maplot
All key parameters at a glance:
res_de: YourDESeqResultsobjectFDR: Which padj cutoff value to set for genes to be counted as DE (default < 0.05)hlines: whether or not (and where) to draw the horizontal line (optional)
Further control on the aspect of the output plot is enabled via the other possible parameters; please refer to the documentation of the plot_ma() function itself.
If desired, plot_ma() further allows you to highlight certain genes of interest to you, if providing them via the intgenes parameter.
maplot_genes <- plot_ma(
res_de = res_macrophage_IFNg_vs_naive,
FDR = 0.1,
add_rug = FALSE,
intgenes = c(
"SLC7A2",
"CFLAR",
"PDK4",
"IFNGR1"
), # suggested genes of interest
hlines = 1,
intgenes_color = "darkblue"
)
maplot_genes
7 Beautifying and enhancing analysis reports
Analysis reports, often generated via Rmarkdown, are a great way of handing over data, results, and output to collaborators, colleagues, PIs, …
mosdef provides a set of functions aiming to enhance the report quality, e.g. by turning normal tables into interactive tables, linking to a number of additional external databases - thus simplifying the search & exploration steps which naturally follow the inspection of a DE table.
7.1 More information on features/genes
The life of a bioinformatician, but also the life of a biologist and a medical scientist, often contains a fair amount of searches into external databases, in order to obtain additional information on the shortlisted features.
Simplifying the time to reach these resources and embedding them into one info-rich analysis report is mosdef’s proposal to streamline this as a whole.
All of these (except ENSEMBL, using their internal identifier system) require gene symbols as the input. Currently, mosdef has functions to create automated links to:
- ENSEMBL (https://www.ensembl.org/index.html)
- GeneCards (https://www.genecards.org/): For information/overview on the gene
- Pubmed (https://pubmed.ncbi.nlm.nih.gov/): For gene/GOterm related publications
- NCBI (https://www.ncbi.nlm.nih.gov/): For overview and chromosomal information on the gene
- dbPTM (https://awi.cuhk.edu.cn/dbPTM/): For post-translational modifications
- GTEX (https://www.gtexportal.org/home/): For data on expression of the gene in different tissues
- UniProt (“https://www.uniprot.org/”): For information on the protein related to the gene
- Human Protein Atlas (“https://www.proteinatlas.org/”): For information on the protein related to the gene for humans specifically
You can access all of these easily by using one function that uses a data.frame as input:
# creating a smaller subset for visualization purposes and to keep the main res_de
res_subset <- deresult_to_df(res_macrophage_IFNg_vs_naive, FDR = 0.05)[1:100, ]
buttonifier(
df = res_subset,
col_to_use = "symbol",
create_buttons_to = c("GC", "NCBI", "GTEX", "UNIPROT", "dbPTM", "HPA", "PUBMED"),
ens_col = "id",
ens_species = "Homo_sapiens"
)Again, an overview of the key parameters:
df: A data.frame object containing your data. To get one from yourDESeqResultsdata use the function:deresult_to_df().col_to_use: Column where the gene names are stored, default is “SYMBOL”, in this example however the column is named “symbol”.create_buttons_to: All of the supported websites. You can pick however many you want.ens_col: Where to find the Ensembl IDs in case you want to turn those into buttons too. If not this defaults to NULL and that part is skipped.ens_species: The species you are working on. Only needed if you want to turn the Ensembl IDs into buttons.
Importantly, the buttonifier() function directly returns a DT::datatable by default (not a data.frame).
This is to ensure that the escape = FALSE parameter of datatable is set and not forgotten as the links/buttons will not work otherwise (or at least, will displayed very oddly as “simple text”, not interpreted as the code to generate buttons).
Advanced users that want further customization options to their datatable can ensure a data.frame is returned using the output_format parameter (then the escape = FALSE must be set by hand):
res_subset <- deresult_to_df(res_macrophage_IFNg_vs_naive, FDR = 0.05)[1:100, ]
res_subset <- buttonifier(res_subset,
col_to_use = "symbol",
create_buttons_to = c("GC", "NCBI", "HPA"),
output_format = "DF"
)
DT::datatable(res_subset,
escape = FALSE,
rownames = FALSE,
# other parameters specifically controlling the look of the DT...
options = list(
scrollX = TRUE
)
)As an additional prettifying element, the information on the log2 fold change can be also encoded with small transparent colored bars, representing the underlying effect sizes.
This can be done with the de_table_painter() function, displayed in the following chunk:
de_table_painter(res_subset,
rounding_digits = 3,
signif_digits = 5)
## This also works directly on the DESeqResults objects:
de_table_painter(res_macrophage_IFNg_vs_naive[1:50, ],
rounding_digits = 3,
signif_digits = 5)All of the functions included inside the buttonifier() function are also available as singular functions in case you are only interested in a subset of them.
As a reminder: all functions, except the one related to the ENSEMBL database, can use/need gene symbols as input, so that the call to build up the table from its individual columns could be specified as in the following chunk:
res_subset <- deresult_to_df(res_macrophage_IFNg_vs_naive, FDR = 0.05)[1:100, ]
row.names(res_subset) <- create_link_ENSEMBL(row.names(res_subset), species = "Homo_sapiens")
res_subset$symbol_GC <- create_link_GeneCards(res_subset$symbol)
res_subset$symbol_PubMed <- create_link_PubMed(res_subset$symbol)
res_subset$symbol_NCBI <- create_link_NCBI(res_subset$symbol)
res_subset$symbol_dbPTM <- create_link_dbPTM(res_subset$symbol)
res_subset$symbol_GTEX <- create_link_GTEX(res_subset$symbol)
res_subset$symbol_UniProt <- create_link_UniProt(res_subset$symbol)
res_subset$symbol_HPA <- create_link_HPA(res_subset$symbol)
DT::datatable(res_subset, escape = FALSE,
options = list(
scrollX = TRUE
)
)For information on singular genes you can use:
geneinfo_to_html("IRF1",
res_de = res_macrophage_IFNg_vs_naive,
col_to_use = "symbol"
)Link to the NCBI Gene database: IRF1@NCBI
Link to the GeneCards database: IRF1@GeneCards
Link to the GTEx Portal: IRF1@GTEX
Link to the UniProt Portal: IRF1@UNIPROT
Link to related articles on Pubmed: IRF1@Pubmed
DE p-value (adjusted): 5.580818e-93
DE log2FoldChange: 5.56
It can however also be used without a res_de for a general overview.
geneinfo_to_html("ACTB")Link to the NCBI Gene database: ACTB@NCBI
Link to the GeneCards database: ACTB@GeneCards
Link to the GTEx Portal: ACTB@GTEX
Link to the UniProt Portal: ACTB@UNIPROT
Link to related articles on Pubmed: ACTB@Pubmed
This can be a practical way to generate some HTML content to be embedded e.g. in other contexts such as dashboards, as it is currently implemented in pcaExplorer, ideal and GeneTonic.
7.2 More information on GO terms
We display an interactive table for a subset of GO terms - in this case, we select the first 100 rows.
res_enrich_macrophage_topGO$GO.ID <- create_link_GO(res_enrich_macrophage_topGO$GO.ID)
DT::datatable(res_enrich_macrophage_topGO[1:100, ],
escape = FALSE,
options = list(
scrollX = TRUE
)
)Setting escape = FALSE is important here to ensure the link is turned into a button - since we are dealing with a datatable where we need to interpret some content directly as HTML code.
To get information on a singular GO term of interest you can use:
go_to_html("GO:0001525")Pubmed results: angiogenesis@Pubmed
Term: angiogenesis
Ontology: BP
Definition: Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.
Synonym: blood vessel formation from pre-existing blood vessels
This not only creates a link to the AmiGO database, but also extracts some information about the term itself from the GO.db package.
This approach can be extended to link to additional external resources on genesets, such as MSigDB or Reactome.
