There are two sets of bug fixes available. One is for Amber and the other
for AmberTools. When reporting patch levels (which is important in this
case), give us the result of the following command:
cd $AMBERHOME && ./patch_amber.py --patch-level
This will tell us how many patches have been applied to both packages. For
reference, the fully-updated tree should return this:
$ ./patch_amber.py --patch-level
Latest patch applied to AmberTools12: 25
Latest patch applied to Amber12: 11
Note, you can also use patch_amber.py to quickly check for available
updates using "./patch_amber.py --check" (see a full listing of options
using --help).
Most notably, bugfix.11 for Amber12 I believe fixes parallel GPU
simulations which may have given NaNs before.
HTH,
