PHG - Error in encodePathArrayFromSet()

Question

[twrl8]

Hello,

I am working on the pathfinding step of the PHG pipeline and am currently trying to resolve a related issue regarding the correct parameters, described here . However when I try to rerun only the pathfinding step I run into the same error repeatedly. I have had the same for a few of my samples before, but now it has occurred the last 3-4 times I tried.

My config is the same as in the previous post (only with changed pathMethod, minReads, probCorrect, outVcfFile, debugDir) and I am still using the same sqlite database and PHG v1.4.

The error I get is the following:

[DefaultDispatcher-worker-1] INFO net.maizegenetics.pangenome.hapCalling.ConvertReadsToPathUsingHMM - Getting path for chromosome UN

After the pathfinding for the last chromosome is done and it tries do encode and compress the path data to store in the database, it runs into an error. I can see in the PHG code where it occurs and my guess would be it is some issue happening with ByteBuffer.allocate(), but since the exception is null and I am not experienced in java, I have trouble figuring out what could be the underlying cause for it. Has anyone encountered this before or has any ideas?

Help is much apprechiated! Thank you!

Will you send me your full log file ([e-mail]) ? I"d like to see if there were other messages in it that may sheds some light on this.
