[gmx-users] trjconv index file

[Rabab Toubar]

Hi,

I want to extract the protein only without the waters. And from the mailing list discussing trjconv, what I did was:

make_ndx -f conf-protein 

trajconv -f pr.trr -n index.ndx -o pr_trj.trr

, but I get file input/output error 

Am I missing something?
Thanks
Rabab Toubar

If you want useful help, you have to tell us exactly what you did - copy and paste command lines and output.

Otherwise, you'll just get people throwing up their hands and giving you a reference to generic material, like http://www.gromacs.org/Documentation/File_Formats/Index_File
