  How can I give a command which initially read the comparisons and it takes that to [metadata][phenotype][embryo] and which takes that to samples -> files ->bam which is the input

[chriswelborn]

This question is difficult to understand. I don't think the wall of output text helps. Maybe you could word it differently, or provide a little pseudo-code to help us understand what exactly you are trying to do?

What are the comparisons? A file?

What does "takes that to [metadata][phenotype][embryo]" mean? (what does "takes that to" mean in python?)

"samples -> files -> bam which is the input"..input to what?

A lot have people have viewed your question, but I think the wording is making it hard to help.
