Input

pattern
meta{:bash}
:map
Groovy Map containing contrast information. This can be used at the
workflow level to pass optional parameters to the module, e.g.
[ id:‘contrast1’, blocking:‘patient’ ] passed in as ext.args like:
‘—blocking_variable $meta.blocking’.
contrast_variable{:bash}
:string
The column in the sample sheet that should be used to define groups for
comparison
reference{:bash}
:string
The value within the contrast_variable column of the sample sheet that
should be used to derive the reference samples
target{:bash}
:string
The value within the contrast_variable column of the sample sheet that
should be used to derive the target samples
formula{:bash}
:string
(Optional) R formula string used for modeling, e.g. ’~ treatment’.
comparison{:bash}
:string
(Optional, mandatory if formula is provided) Literal string for contrasts, e.g. ‘treatmenthND6’.
meta2{:bash}
:map
Groovy map containing study-wide metadata related to the sample sheet
and matrix
samplesheet{:bash}
:file
CSV or TSV format sample sheet with sample metadata
counts{:bash}
:file
Raw TSV or CSV format expression matrix as output from the nf-core
RNA-seq workflow
meta3{:bash}
:file
Meta map describing control genes, e.g. [ id: ‘ERCC’ ]
control_genes_file{:bash}
:file
Text file listing control genes, one per line
meta4{:bash}
:map
Groovy map containing study-wide metadata related to the transcript
lengths file
transcript_lengths_file{:bash}
:file
Optional file of transcript lengths, with the same sample columns as
counts. If supplied, lengths will be supplied to DESeq2 to correct for
differences in average transcript lengths across samples.
