hello,
I am trying to simulate streptavidin tetramer-biotin complex.I ve calculated Ligand topology from a sofware PRODRG using gromos87 force fields.After solvating it,I am getting an error using grompp command

Fatal error:
Atomtype HW not found

can anyone provide me some help?


The HW type is specific for the Gromos87 force field (i.e. gmx.ff in Gromacs), so if you're getting this fatal error, you're somehow mixing and matching force fields, likely between Gromos87 and Gromos96.
