Hi,
I need to add Zn2+ and Mg2+ ions to my system of protein. However, running the gmx grompp command its showing me the following error:
Fatal error:
number of coordinates in coordinate file (solv.gro, 178616)
does not match topology (topol.top, 178620)
I calculated the number of atoms in both the files and its 178616 in both. Why is this error showing and how do I fix it ?
