WDL: how to use scatter for multiple callers?

Question

[c.clarido]

Good day,

I have a bam file and 3 callers (delly,clever and lumpy) to detect structural variants and then use a tool (survivor) to merge the files.

I was wondering if there is a way to use scatter in WDL so that the three callers will each ouput a VCF file?

Kind regards, C.agaser

I missed something. WDL can't tell the callers what to output, it only collects their output, if you'll define the vcf as output you could use that file later in the analysis. It is not scatter-gather though, just linear execution.
