FYI, you can use the editconf script to convert a pdb file to gro. Did you visualise the molecules at this point? > 4. Merge molecules back together into a single complex > .gro file (again, hoping the coordinates are > preserved) If you see things all messed up at this point, with them fine before merging, then as Erik noted, you have messed up the gro file format when merging the two molecules into one file.
