Not completed in overlap_collect step

[kjyunm]

Hello,
I am trying to build a pangenome using pig data from multiple breeds. The input data is 4.5GB when compressed, and I am using the Docker image ghcr.io/pangenome/pggb:latest.

I ran the following command
docker run -it -v ${PWD}:/data -u $(id -u):$(id -g) ghcr.io/pangenome/pggb:latest pggb -i /data/pigs.assembly.fa.gz -o /data/out -t 20

However, during the execution, it gets stuck at the step
[seqwish::transclosure] 25082.955 81.34% 12280027975-12290027975 overlap_collect
and has not progressed for over a week.

Could you please advise if there are any additional options or preprocessing steps needed to resolve this issue? I would appreciate any suggestions on the cause of this hanging and how to resolve it.

Thank you!
