[gmx-users] query about resuming a crashed mdrun

[Mark Abraham]

Hi,

Your second command didn't use deffnm flag, so mdrun interpreted your
intent as wanting most of the files to be named as the default. The 2016
release series refuses to run your second command precisely because of the
ambiguity about whether you intend to append, change names, etc.
