Problem in creating consensus ATAC peaks

[gauriprasad08]

Hi,

I used the project pipeline of PEPATAC to create consensus ATAC peaks for my samples.I get the combined summary stats for all samples (PEPATAC_tutorial_stats_summary.tsv). However, the pipeline fails to run the PEPATAC_collator and do not produce the consensus peaks. I have attached a PEPATAC_collator_log.md file for your reference.

The error does not seem to indicate that any component is missing from the installation, so most likely it is due to a certain feature in my data that the PEPATAC "does not like". But What is that feature is not clear to me?

Kindly help me out to solve this issue.

This script is choking when trying to read in a file. Could it be an empty file? Or is it possible one of your sample names has a space in it?

Hi. Thanks for raising this point. I checked my files one by one. None of the files is empty or with space in its name.

Ah, I think I see something. Do you have multiple genomes in this PEP?

You cannot call consensus peaks if the reference genome isn't identical across all samples.
