1 Installation
We recommend installing the stable release version of PhIPData in Bioconductor.
This can be done using BiocManager:
if (!require("BiocManager"))
install.packages("BiocManager")
BiocManager::install("PhIPData")To load the package:
library(PhIPData)2 Introduction
The PhIPData class is used to store experimental results from phage-immunoprecipitation sequencing (PhIP-set) experiments in a matrix-like container.
Building on the RangedSummarizedExperiment class, PhIPData contains all of functionality of SummarizedExperiments and includes additional operations to facilitate analysis with PhIP-seq data. Like SummarizedExperiments, a key feature of PhIPData is the coordination of metadata when subsetting PhIPData objects. For example, if you wanted to examine experimental data for peptides from one particular virus, you can subset the experimental data and the associated peptide annotation with one command. This ensures all metadata (for samples, peptides, etc.) remain synced with the experimental data throughout analysis.
3 Components of a PhIPData Object
As reflected in the figure below, the structure of a PhIPData object is nearly identical to the structure of a SummarizedExperiment/RangedSummarizedExperiment object.
Each object contains at least three assays of data. These assays are:
counts: matrix of raw read counts,logfc: matrix of log2 estimated fold-changes (in comparison to negative control samples),prob: matrix of probabilities (p-values or posterior probabilities) associated with whether a sample shows an enriched antibody response to the particular peptide.
Though counts typically contain integer values for the number of reads aligned to each peptide, PhIPData only requires that stored values are non-negative numeric values. Pseudocounts or non-integer count values can also be stored in the counts assay.
The rows of a PhIPData object represent peptides of interest and the columns represent samples. Sample and peptide metadata are stored in DataFrames. Each row of the metadata DataFrame specifies the peptide/sample, and the columns represent different features associated with the peptides/samples.
In addition to sample- and peptide-specific metadata, experimental metadata such as associated papers, experimental parameters, sequencing dates, etc. are stored in a list-like component named metadata.
Figure 1: Schematic of a PhIPData object
Commands used to access each component of the object are listed underneath its visual representation. Code in black indicates functions specific to PhIPData objects while functions in red extend SummarizedExperiment functions. Here, pd is a generic PhIPData object.
4 Creating a PhIPData object
library(dplyr)
library(readr)To demonstrate the PhIPData class and functions, we will use a simulated example data set. Suppose we have PhIP-seq data from 5 individuals for 1288 peptides derived from known human viruses.

5 Accessing and modifying components of PhIPData object
5.1 Assays
Assays store matrix-like data. For PhIPData objects, the assays counts, logfc, and prob are required. If any of these matrices were missing from the constructor, they are initialized with empty matrices of the same dimensions. Experimental data can be accessed via assays(phip_obj) or assay(phip_obj, i) command. assays(phip_obj) returns a list of all assays in the object, and list items can be accessed using the $ or [[ operators.
assays(phip_obj)## List of length 3

## pep_6 69802 419044 693736 177505 332696While assays(phip_obj) returns a list of all assays in the PhIPData object, assay(phip_obj, i) returns a matrix of the specified assay. If i is missing, assay(phip_obj) defaults to the first assay (counts). i can be a character specifying the assay name or a numeric index of the assay.

Dimension names of the replacement assays are automatically corrected to be identical to the object names. As we expect assays to contain homogenous data, replacement assays are coerced into matrices. Replacement assays must also be on the same dimension of the existing object.

Information associated with peptides can be accessed using peptideInfo(phip_obj) or the inherited rowRanges(phip_obj) function. Both functions return a GRanges object. GRanges objects behave similar to matrices and can be subsetted using the usual 2-dimensional methods. More information about GRanges objects can be found here.
Information about peptide positions in the protein sequence are stored as IRanges in the GRanges object. These are specified by pos_start and pos_end columns in the peptide metadata in the constructor. If these columns do not exist, the start and end positions are set to 0 by default.

Sample metadata describing the samples can be extracted from the PhIPData object using sampleInfo(phip_obj) or the inherited function colData(phip_obj). Both functions return a DataFrame where each row corresponds to a sample and each column corresponds to some sample description.
sampleInfo(phip_obj)## DataFrame with 5 rows and 3 columns
## sample_name gender group
## <character> <character> <character>
## sample_1 sample1 M ctrl
## sample_2 sample2 F beads
## sample_3 sample3 F trt
## sample_4 sample4 F trt
## sample_5 sample5 M trtLike in SummarizedExperiments/RangedSummarizedExperiments, sample metadata can be accessed using the $ operator from the object. As demonstrated in the Subsetting section, this makes subetting data for a subgroup of samples very easy.
phip_obj$group## [1] "ctrl" "beads" "trt" "trt" "trt"5.4 Experimental metadata
Data associated with the experiment such as papers, date the samples were run, etc. can be accessed via the metadata(phip_obj) function. Experimental metadata is stored as a list, so it can be used to store any type of data.
metadata(phip_obj)## $date_run

To assess the quality of the data, we are often interested in the number of reads per sample. This can be done using the librarySize() function. Names can be removed by setting the withDimnames parameter to FALSE.

## 1220 1220 1220 1220 1220The proportion of sample reads pulled by each peptide can also be obtained via propReads(). Like librarySize(), names can also be removed by setting withDimnames to FALSE.

Rather than re-importing peptide annotations, PhIPData allows the user to create and reuse existing libraries. To save a library for future use, we can use makeLibrary(object, name_of_library). The peptide metadata should be in a matrix-like form such as a DataFrame or data.frame.
# Save virscan_info as the human_virus library
makeLibrary(virscan_info, "human_virus")The stored library can be accessed using getLibrary(library_name). We can then use the stored library to construct a new PhIPData object as follows.
PhIPData(counts = counts_dat,
sampleInfo = sample_meta,
peptideInfo = getLibrary("human_virus"))## ! Missing peptide start and end position information. Replacing missing values with 0.## class: PhIPData

removeLibrary("human_virus")6.4 Using aliases
Peptides are often derived from species with long virus names. To quickly search up all viruses with “[Hh]uman immunodeficiency virus” in the species, you can create an alias of “HIV” to encode for the corresponding regex of interest. Alias’s can be managed with:
getAlias(key): return the regex for the aliaskey.setAlias(key, pattern): create or modify the alias forkey. If the key-pattern combination already exists in the database, then no changes are made. Otherwise, the pattern is replaced withpattern.deleteAlias(key): remove an key-pattern combination from the alias database.
# Create alias for HIV ----------
setAlias("hiv", "[Hh]uman immunodeficiency virus")
# Use alias ----------
hiv_sub <- subset(phip_obj, grepl(getAlias("hiv"), species))

## beads-only name(1): beadsAlias-pattern combinations are case senstive, so an entry with key “hiv” would differ from an entry with key “HIV.” Like libraries, by default the location of the alias database is in the extdata folder of the PhIPData package. The location to an .rda file with the key-pattern values in a dataframe called alias can be retreived and specified using the getAliasPath() and setAliasPath() functions, respectively.
6.5 Coercion from PhIPData to other containers
As packages for identifying differential experession are also commonly used in analyzing PhIP-seq data, the PhIPData package supports coercion from PhIPData objects to Lists, lists, DataFrame, and DGELists. The function as(phip_obj, "object_type") converts a PhIPData object to a object of object type.
For DGELists, the group slot is automatically populated with the group column in the sample metadata, if such a column exists.
# PhIPData to DGEList

Any additional list/object components may be discarded.
