Re: [gmx-users] extract chain information in xtc file
Dear Tina, No need to extract subtrajectories, just create index concerning the separated chains you want to use, and perform the calculation in gromacs. Happy modelling!

I found several information for concatenation or even to cut a simulation of time N in several simulations of time n, but I do not find anything concerning a possible cut according to the chains of the molecule.

Re: [gmx-users] extract chain information in xtc file
Hi Make use of gmx make_ndx option. Please refer the manual to use it. You can define your chain there and extract it separately On Tue 26 Mar, 2019, 6:49 PM , wrote: > Hello, > I barely discover Gromacs and I have to use it to study trajectory > results, so I wanted to know if it was possible from an xtc file to > generate several xtc files, one for each chain of the molecule that we want > to study, (in order to retrieve information and perform calculations) and > if it is possible, how?

[gmx-users] extract chain information in xtc file
Hello, I barely discover Gromacs and I have to use it to study trajectory results, so I wanted to know if it was possible from an xtc file to generate several xtc files, one for each chain of the molecule that we want to study, (in order to retrieve information and perform calculations) and if it is possible, how? I found several information for concatenation or even to cut a simulation of time N in several simulations of time n, but I do not find anything concerning a possible cut according to the chains of the molecule.
