Hi Sajad,<br><br>The error seems quite explicit. The input file to grep does not exist.<br>Are you in the right directory? Are you mixing op O and 0?<br><br>Also, please note that this has nothing to do with gromacs. This is<br>just your basic linux and this mailing list is the wrong place for<br>such questions. Furthermore, to omit TPO, you need to run grep -v<br>'TPO' 10L5.pdb > No-TPO.pdb<br><br>Hope it helps,<br><br>Tsjerk<br><br>On Sun, Apr 17, 2011 at 12:09 PM, Sajad Ahrari <<a ymailto="mailto:sajadahrari@yahoo.com" href="mailto:sajadahrari@yahoo.com">sajadahrari@yahoo.com</a>> wrote:<br>> hello every one!<br>> I am trying to omit TPO(witch stands for phospho-tyrosine) from my pdb file<br>> by executing the command"grep TPO 10L5.pdb > TPO.pdb". but i am being facing<br>> with this erorr"grep: 10L5.pdb: No such file or directory" can any one help?<br>><br>><br>> --<br>> gmx-users mailing list <a
