Scatter:Gather by array indices

ericco92ericco92 Cambridge, UKMember ✭✭

I have multiple use cases where I'd like to iterate over the indices of multiple same-size arrays (e.g. when aligning paired fastq files or slices of tumor / normal BAMs). Is this something that's supported by Cromwell / FireCloud? I can't seem to find anything regarding it in the docs.

    Thanks @ChrisL ! I didn't realize WDL had range/zip functions. Just to be sure - are they FireCloud compatible?

    Yes- those functions should all be fully functioning in Firecloud!
