fastqc

This function calls
<a href="https://www.bioinformatics.babraham.ac.uk/projects/fastqc/">fastqc</a> using
<code><a href="/link/system2()?package=seeker&version=1.1.6" data-mini-rdoc="seeker::system2()">system2()</a></code>. To run in parallel, register a parallel backend, e.g., using
<code>doParallel::registerDoParallel()</code>.

Wrapper around various existing tools and command-line interfaces,
providing a standard interface, simple parallelization, and detailed logging.
For microarray data, maps probe sets to standard gene IDs, building on
'GEOquery' Davis and Meltzer (2007) <doi:10.1093/bioinformatics/btm254>,
'ArrayExpress' Kauffmann et al. (2009) <doi:10.1093/bioinformatics/btp354>,
Robust multi-array average 'RMA' Irizarry et al. (2003) <doi:10.1093/biostatistics/4.2.249>,
and 'BrainArray' Dai et al. (2005) <doi:10.1093/nar/gni179>.
For RNA-seq data, fetches metadata and raw reads from National Center for Biotechnology
Information (NCBI) Sequence Read Archive (SRA), performs standard adapter and
quality trimming using 'TrimGalore' Krueger <https://github.com/FelixKrueger/TrimGalore>,
performs quality control checks using 'FastQC' Andrews <https://github.com/s-andrews/FastQC>,
quantifies transcript abundances using 'salmon' Patro et al. (2017) <doi:10.1038/nmeth.4197> and potentially
'refgenie' Stolarczyk et al. (2020) <doi:10.1093/gigascience/giz149>,
aggregates the results using 'MultiQC' Ewels et al. (2016) <doi:10.1093/bioinformatics/btw354>,
maps transcripts to genes using 'biomaRt' Durinkck et al. (2009) <doi:10.1038/nprot.2009.97>,
and summarizes transcript-level quantifications for gene-level analyses using
'tximport' Soneson et al. (2015) <doi:10.12688/f1000research.7563.2>.

should be a single filepath. For paired-end reads, each element can be two
filepaths separated by ";".</dd>
