htmlReport: HTML-Report Builder for the AVASet and MapperSet

In R453Plus1Toolbox: A package for importing and analyzing data from Roche's Genome Sequencer System

Description

This function creates a HTML variant and quality report for a given AVASet or MapperSet instance.

Usage

htmlReport(object, annot, blocks=c(), transcripts=c(), sampleCols, minMut=3, dir="HTMLReport", title="Summary")

Arguments

object	An AVASet-class or MapperSet-class instance.
annot	An instance of class AnnotatedVariants you get by calling annotateVariants. If no such argument is supplied the data will be read from the Ensembl database automatically for all variants.
blocks	Character vector of block names for each variant. The variants will then be structured into several blocks. If no such list is supplied, the report consists of just one (big) table for all variants.
transcripts	Character vector containing Ensembl transcript-IDs that order the according entries on the transcript pages. Transcripts given in this argument will appear on top of the transcript page.
sampleCols	Character vector of column names of the sample data (phenoData) of the AVASet/MapperSet object to filter the sample output on the transcript pages. All columns will be listed if no such argument is given.
minMut	If the value of minMut is greater than zero, the report lists only variants, whose coverage for at least one sample is higher than minMut (percentage between 0 and 100).
dir	Character with the desired output directory. By defaultm the directory "HTMLReport" will be created in the current directory.
title	Heading for the first page with the variant information.

Details

The report is structured into two (MapperSet) or three (AVASet) parts containing variant and quality information:

• The main page sums up given variant information like the name, type, reference gene, position (see fData, annotateVariants).
  Using the argument blocks, the main page can be individually structured by assigning a block name to each variant.
  The main page can be further structured by samples. For a given AVASet object, every sample links to another short quality report showing only the amplicon coverage for this sample.

• Every variant on the main page links to a page with further details about the affected genes and transcripts (e.g. Ensembl gene-IDs, transcript-IDs, codon sequences, changes of amino acids (if coding)).

• Only in case of AVASet object: A quality report shows the coverage of every amplicon in forward and/or reverse direction. Further plots display the coverage by MID and PTP (if this information is given in the pheno data of the object).

Examples

# note: all examples save the report to the directory "htmlReportExample" in your current R working directory

# load a filtered AVA dataset containing 6 samples, 4 amplicons and 4 variants
# and its variant annotations
data("avaSetFiltered")
data("avaSetFiltered_annot")

# create a full report showing all (unfiltered) information
htmlReport(avaSetFiltered, avaSetFiltered_annot, dir="htmlReportExample", title="htmlReport Example", minMut=0)
# create a report that emphasizes on samples with variants covered by at least 50% of the reads 
htmlReport(avaSetFiltered, avaSetFiltered_annot, dir="htmlReportExample", title="htmlReport Example", minMut=50)

# create a report that is structured by the reference genes
library("ShortRead")
refs = sapply(fData(avaSetFiltered)$referenceSeq, function(x) 
    subset(pData(alignData(referenceSequences(avaSetFiltered))), pData(alignData(referenceSequences(avaSetFiltered)))$refSeqID == x)$name)
htmlReport(avaSetFiltered, avaSetFiltered_annot, dir="htmlReportExample", title="htmlReport Example", minMut=0, blocks=refs)

# create a report whose sample information only lists the sample ids
pData(avaSetFiltered)
sampleCols = "SampleID"
htmlReport(avaSetFiltered, avaSetFiltered_annot, dir="htmlReportExample", title="htmlReport Example", minMut=0, sampleCols=sampleCols)
