I extracted [was instructed to extract] trajectory frames at every 10 ps from a 10ns xtc file and energy minimized each of them. How do I cluster them? I tried to do ls *.gro | gmx cluster -f {.}.gro , did not work. I concatenated the frames and made an xtc file and tried to cluster it in

Hello all, I have generated a PDB file for Inositol pyrophosphate using pyMOL to build the structure from scratch. I have converted PDB to mol2 with openbabel and submitted at Swissparam (http://swissparam.ch/) which returned a zip file containing various files of the same name (.itp,
