Re: [AMBER] trajectory of minimization using generalized Born

Hello, thank you for your replies.

I am using Amber 12.0 on a cluster running Scientific Linux 6.6 (kernel
2.6.32-504.3.3) and manages jobs using torque.

I got the following message when loading amber:

module load apps/amber/v12.0
Amber and AmberTools v12.0 serial and parallel
OpenMPI v1.6.3 for Intel 2013.0.079 with torque and infiniband support
Intel compilers v2013.0.079

I haven't found update_amber anywhere, maybe the administrator deleted it.
I looked for it using:
find /gpfs/apps/amber/amber12.0/ -iname \*update\*

Is there any other way I can check the patches applied?

I am getting an ERROR IN SETPAR() in the .out file:

 &cntrl


imin=1,


maxcyc=2000,


ncyc=1000,


cut=999.,


rgbmax=999.,

ntpr=50,


ntwx=50,


ioutfm=1,
