Hi I read your comment..... "This is a comment line to the previous one. The angle is between the three atoms mentioned. it is an index in another array in the gROMOS96 files (not part of gromacs) ."
But, I did not understand...... #define ga_24 120 505 ; H - N - CH3. H, HC-6-ring, H-NT-CHn 90 I still confuse with the comma "," and " - " does it mean ? =>H - N - CH3 ( the angle between H - N - CH3, right?) H - N - H, H - N - (HC-6-ring) H - N - CHn (HC-6-ring) - NT -CHn CH3 - NT - CHn thank you Lin _______________________________________________ gmx-users mailing list gmx-users@gromacs.org http://www.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
