Dear all,

I am trying to do simulation of DNA-protein complex . For this purpose I am using " ffoplsaano force field" which is already charged with ffamber force field which I have got from golovin_at_genebee.msu.su <http://golovin_at_genebee.msu.su> website . I am using this force field with pdb2gmx command but I am getting error like this -

Error in hdb file ffoplsaano.hdb:
Wrong number of control atoms (3 iso 4) on line:
1 5 H4* C4* O4* C5*
Can anyone suggest me how can I solve this problem?


Read the manual - section 5.6.2. The .hdb file you are using is improperly formatted. You have 3 "instead of (iso) 4" atoms that are the reference for adding the hydrogen.

Thank you very much in advance.
