Justin, thanks again for explanation. So the first 5 atoms in cmap.it correspond to the starting sequence of the backbone atoms of the amino acid doesnt it ? So what is the 24 24 numbers at the end of each cmap line ? E.g in the C NH1 CT1 C NC=O 1 24 24\ the first C B CA C N atoms would be assig

Dear francesco I extract gold parameter from papers that I attached them for you. But  for gold and other atom parameters, you should calculate them using common combination rule. Fatemeh Ramezani -- gmx-users mailing listgmx-users@gromacs.org http://l

Hi fatemeh, thank you for the references. Regarding your problem, what does it means you don't see any interaction? Is it possible it is just a problem of the visualization software. To be sure, you could monitor the distance between any S atom and the Au atom to which it is supposed to be bound. I

[gmx-users] Box Pressure on individual box walls

Dear All, I am practising the tutorial 2 of Gromacs ( KALP-15 in DPPC). In the step "Solvate with water",i made a copy of vdwradii.dat and changed the value of C from 0.15 to 0.375. But i don't know how to input this changed file into genbox. I saw genbox -h, and i don't find any option for input
