Thank you very much, David and Yang Ye! It works perfectly with the following syntax:
echo "1 \n" | tjrconv -f -s -o -sub myFrames.ndx ..where myFrames.ndx looks like: [protein] 1 3 6 7 8 etc. : numbers of the frames to be written (not time in ps) (generated by one of my perl scripts) apparently same result with echo "1" | tjrconv -f -s -o -fr myFrames.ndx Best regards, Pascal ******************************************************************************* Pascal Baillod (PhD student) ******************************************************************************* Swiss Federal Institute of Technology EPFL Tel: +41-(0)21-693-0322 Institute of Chemical Sciences and Engineering , Fax: +41-(0)21-693-0320 Laboratory of Computational Chemistry and Biochemistry [EMAIL PROTECTED] Room BCH 4121, Avenue Forel, http://lcbcpc21.epfl.ch CH-1015 Lausanne ******************************************************************************* _______________________________________________ gmx-users mailing list [email protected] http://www.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
