File Pairs as process input, DSL2

[Adam Streck]

Consider the example of the Channel.fromFilePairs as given here:

https://www.nextflow.io/docs/latest/channel.html#fromfilepairs

load this data into a variable DATA, i.e. DATA.view() prints:

[SRR493366, [/my/data/SRR493366_1.fastq, /my/data/SRR493366_2.fastq]] [SRR493367, [/my/data/SRR493367_1.fastq, /my/data/SRR493367_2.fastq]] [SRR493368, [/my/data/SRR493368_1.fastq, /my/data/SRR493368_2.fastq]] [SRR493369, [/my/data/SRR493369_1.fastq, /my/data/SRR493369_2.fastq]] [SRR493370, [/my/data/SRR493370_1.fastq, /my/data/SRR493370_2.fastq]] [SRR493371, [/my/data/SRR493371_1.fastq, /my/data/SRR493371_2.fastq]]

how can I create a process that takes DATA as an input? If there was just one file per name, I can do:

input:
tuple val(name), path(file)

however for the two files neither:

input:
tuple val(name), path(file1), path(file2)

nor:

input:
tuple val(name), tuple(path(file1), path(file2))

work.
