Inquiry Regarding IOError Encountered During Multiple Rounds of Merging gVCF Files Using GLnexus

[zhanxiangzong]

Hi!

Thank you for providing this tool.

I encountered a minor issue while using GLnexus and would like to seek your guidance.

Initially, I used GLnexus to merge five datasets, each consisting of several hundred gVCFs, and this process was completed without any problems. However, after converting the five merged BCFs back to gVCFs and attempting to merge these five files again using GLnexus, I encountered a failure during the "discovering alleles" step.

Here are the details of the error message:

Can you help me resolve this issue? Or is it the case that GLnexus cannot merge gVCF files that already contain multiple samples?

Thank you in advance for your help!

I saw issues about this error one year ago, and it has not been replied yet. Have they abandoned this package?
