okey.. I got it under control. The problem was. 1. created a good box widths.. went upto 30nm with editconf and box vector 2. (Made a mistake while adding ions with genion): saved the file as pdb instead of gro!! 3. was trying grompp with the pdb file (So I have no idea what grommp found different in a file with/witout ions) Thanks for hinting on the last line of gro. (still I think it is probably a bug or feature)
