Hi Thomas,
Sometimes, when there are many thousands of groups in the model.star
files, and the data.star is very long (because of millions of particles)
reading those back in can take some time. Many hours sounds a bit too long
though. Perhaps the job is just stuck for some other reason?
HTH,
Sjors
