[gmx-users] Regarding error.

[Dylan Smith]

Hi Suryanarayana,

http://www.gromacs.org/Documentation/Errors is where i'd start. But to help 
you along this error suggests that you have a different number of atoms in 
your coordinate file(.gro) than your topology(.top) suggests. Often this can 
be caused by adding or removing ions or solvent without modifying your .top 
file.

Regards,
Dylan Smith
