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

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

[gmx-users] Re:
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?)
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.
