Hi Sajad,

The error seems quite explicit. 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
