usually I use a command like this to create compressed trajectory dump files:
dump dumpName all atom 10000 filename.gz
In most cases this works well. However, the gzip file seems to be unreadable during the simulation (with errors like
gzip: filename.gz: unexpected end of file). That means I can’t check the trajectory in the middle of a simulation. It also means if the simulation is terminated halfway (e.g. because of power loss, hardware failure, or I manually terminate it), I have to rerun the whole simulation instead of restarting at the breaking point.
So I’m wondering is there any method to save compressed dump files that are readable during a long simulation, or anyway to fix those “corrupted” gzip files.
