[gmx-users] problem in NPT equilibration step

2013-10-14 Thread Preeti Choudhary
Dear Gromacs user, I am trying to simulate a protein (nmr structure).I have successfully done energy minimisation step.Also I have equilibrated the system a 298 k (which is achieved from 100 ps run) .Now,I am trying to equilibrate the system at 1 bar pressure.After a run of 100 ps ,I am getting av

hello everyone I am trying to cluster my data using g_cluster.I simulated the whole protein. I did the g_cluster analysis with only certain region of the protein which I specified using an index file.The program runs fine and gives 1 cluster.My concern is the warning it gives which states that :-

[gmx-users] random seed in molecular dynamics

2013-05-02 Thread Preeti Choudhary
hey this is regarding random seed used in md.this is when it selects the intial velocity and selects from maxwell-istribution.but is it selects only once or selects this random seed every time when grompp makes .tpr file.really confused about this random seed concept.can u clear my confusion?? -th
