Hi
My pdb file comes from a result of an MD calculation with Amber.
i have cut out part of if with vmd. To this new part, ie my new pdb file
(created with amber) i want a prmtop and an inpcrd files, what to do?
Amber is adding to it loads of H atoms again when I load it to xleap, and then
complains about new atom types when I try to create prmtop and inpcrd....
