[gmx-users] Error on Box Length when adding ions (gromacs 4.5.3/Charmm27/Tip3p)

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)
