Dear Chris very thanks for your time and attention.
only difference between what you said and what I did is in the location of template directory: for me >>>>>>>>>>>> gromacs-4.0.7/share/template for you >>>>>>>>>>>> gromacs-4.0.7/exec/share/gromacs/template in my gromacs there is not exec directory even in fresh and original version of gromacs4.0.7. I did rest of the steps exactly as you said. what is your mean of (Did you do the compilation of gromacs)? make -f Makefile.my_tool? Yes I did. I will test all of steps on fresh version of gromacs4.0.7. I hope that solve my problem. after (download a fresh version of gromacs4.0.7, name it with a special directory, make the modification directly to the *original* trjconv, and compile it. Now you will have a special version of trjconv.) I should install gromacs. is it true? -- 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!
