The input file to grep does not exist. Are you in the right directory? Are you mixing op O and 0? Also, please note that this has nothing to do with gromacs. This is just your basic linux and this mailing list is the wrong place for such questions. Furthermore, to omit TPO, you need to run grep -v 'TPO' 10L5.pdb > No-TPO.pdb Hope it helps, Tsjerk On Sun, Apr 17, 2011 at 12:09 PM, Sajad Ahrari <sajadahr...@yahoo.com> wrote: > hello every one! > I am trying to omit TPO(witch stands for phospho-tyrosine) from my pdb file > by executing the command"grep TPO 10L5.pdb > TPO.pdb". but i am being facing > with this erorr"grep: 10L5.pdb: No such file or directory" can any one help? > > > -- > gmx-users mailing list gmx-users@gromacs.org > http://lists.gromacs.org/mailman/listinfo/gmx-users > Please search the archive at > http://www.gromacs.org/Support/Mailing_Lists/Search before posting! > Please don't post (un)subscribe requests to the list.
