[ccp4bb] How to create electrostatic surface of modified DNA by APBS?

2014-04-24 Thread Xiaoming Ren
Dear all: I'm having a problem create the electrostatic surface for a DNA chain containing several modified nucleotides. APBS could not identify those residues and reported them as unassigned. What should I do to solve this problem? Thanks a lot and best, Xiaoming

Hi, It's pdb2pqr problem (unknown residue). I guess you ran pdb2pqr prior to running APBS, if not, you should. So, you should submit your question to either the APBS or pdb2pqr BB's. They are very helpful people. Cheers, Boaz Boaz Shaanan, Ph.D. Dept. of Life Sciences

Hi Xiaoming, I would download pdb2pqr 1.8 from the apbs website and install it. (linux) It can handle nucleic acid, (3 letter code) . After you installed it run it with python /whereeveritis/pdb2pqr-1.8/pdb2pqr.py -h it will print the options. Hope this helps. Fred
