Problem with Amber Parameter generation of Protein containing Mg+2 AND GTP

04 April 2013 0 10K Report

I am getting an error about bond and angle parameter of MG -O-P5 in Amber. I don't know how Mg ion is treated along with GTP in protein complex. I have generated separate parameters for GTP and Mg+2 ion but when I am reassembling the entire complex and giving command Saveamberparam, then there is an error .

MG-O bond parameter missing

MG-O-P5 angle parameter missing

Parameters not saved.

Can anyone help?
