Dear Developers, I am facing problem of incomplete docking. The error statement is pasted below. Also attaching receptor and ligand file for your perusal. Since I am new to this software therefore, detailed explanation is requested in eliminating the problem. #0, chain A: prostaglandin G/H synthase 1 Model 0 (oxidoreductase.pdb) appears to be a protein without secondary structure assignments. Automatically computing assignments using 'ksdssp' and parameter values: energy cutoff -0.5 minimum helix length 3 minimum strand length 3 Use command 'help ksdssp' for more information.
