[gmx-users] Still having issues analyzing normal-mode hessian

2013-05-06 Thread Bryan Roessler
Hello,

I have successfully generated a 945MB mtx hessian storing the normal modes
of a ~1500AA protein using mdrun with the "nm" integrator and no cutoffs.
However, when I try to analyze the normal modes and create trajectories
using g_nmeig, I can't seem to generate any output. I am running
g_nmeig_mpi_d  with the following options: "mpiexec_mpt g_nmeig_mpi_d -f
input.mtx -s NMA.tpr -of NMA_freq.xvg -ol NMA_val.xvg -v NMA_vec.trr" and
have been letting it run a few times for up to 5 days on 128 Itanium nodes
with 120gb maximum memory. When the job finally aborts after running out of
cpu time, I get a standard output file that's about 8GB (which I am unable
to open). Is there a way to force g_nmeig to generate some output or at
least show me what is going on? Am I running it with the correct options?
There isn't a lot of documentation on these normal-mode specific programs
so I don't know how to begin troubleshooting.

Thanks,

Re: [gmx-users] Normal Mode Analysis -- Expected Output

2013-04-12 Thread Bryan Roessler
My problem was here:

>nsteps  = 10
which should read
nsteps  = 1

I was under the assumption that the step numbers would correspond to the
number of calculated eigenvectors. All eigenvectors are calculated in step
1.

Thanks,

Bryan

Thank you for your response. I am running double precision gromacs and I
have minimized my structure down to ~1 Fmax, so neither of those concerns
should be a problem.

[gmx-users] ATP all-atom FF in GROMACS (CHARMM36?)

2013-02-19 Thread Bryan Roessler
Hello,

I am trying to locate an all-atom FF for ATP that I can use in GROMACS. The
ATP residue is stored in a toppar stream file in CHARMM, thus it is not
included in the download on the user-submission page for FFs. It also
appears that it is not available in the AMBER forcefields.

It is however, present in the GROMOS FF supplied with GROMACS and also
available on the user-submission website. However, I have reservations
about using a united-atom FF in conjunction with CHARMM (which is how the
rest of my system is parameterized). I've also taken a PDB of ATP and
parameterized it with SWISS-PARAM, however the user-submitted
'CHARMM2GROMACS' scripts are not successfully parsing the
topology/parameter files and not generating valid GROMACS output.

If anyone has a CHARMM FF for ATP that is in >GROMACS4.5.4 format, I would
be much obliged. If it is not available, I could use some help in
understanding how to convert toppar stream entries from CHARMM into the
GROMACS format.


Thank you,
