[gmx-users] PBC after energy minimization
Hello everybody, In order to solve the PBC at the end I use the command: *gmx trjconv -s md_0_1.tpr -f md_0_1.xtc -o md_noPBC.xtc -pbc mol * followed by: *gmx trjconv -s md_0_1.tpr -f md_noPBC.xtc -o md_noPBC.pdb* I want to solve this problem after the energy minimization but I don't have .xtc file to use it as I do at the end. How can I solve this problem after the energy minimization ?

Re: [gmx-users] about how to create angle.index with specific angles
Dear Dr. Lemkul I did it. It works. Thank you very much for the advise. Now I am having issues opening the (.xpm) files generated that contain for example the gibbs energy landscape on the two first eigenvectors of the dPCA. If I use the command "gmx xpm2ps -f gibbs-1_2.xpm -w yes -o gibbs-1_2.eps" it write this error: "Input error or input inconsistency: Invalid XPixMap" Do you know if I am missing something here? Do I have to install something in my OS to be able to see .xpm images?

I have shared the file on the following link:- https://www.dropbox.com/s/c6tg9q4i0ara3vu/atomtypes.atp?dl=0 There's a lot to go through here with multiple ligands so I'm not going to be able to go through your files line-by-line. You have duplicate bond entries somewhere. Make your system simpler. Run *only* one ligand at a time through pdb2gmx to figure out which one is triggering the problem. Also note that you should remove the extraneous number 1 from all your [ bonds ] lines in your .rtp entries. They're going to lead to incorrect format in the resulting topology. Just specify the pairs of atoms that are bonded. -Justin -- == Justin A.
