[gmx-users] convert xtc to ASCII file

Hello all,

I've been wondering if there is a way to convert a Gromacs xtc trajectory to a plain text file. I've tried Openbabel as it appears to be possible but unfortunately it crashes without a warning. Is there maybe a Gromacs tool that can do the conversion?

Also, as I'm interested in writing only the carbon atoms and not the hydrogens, I've looked at trjconv to see if I could at least do the selection of atoms using that, as it's specified in trjconv's manual that it can select a subset of atoms. However I've been looking at how to do that but I can't find it in the help menu of the program, so  I was wondering if it's not as straightforward as just selecting a subset of atoms through trjconv and maybe it can olny be done after writing a suitable index file?

Any hints would be greatly appreciated :)

Thank you all very much in advance.
