Hii friends,
I want to do simulation of a RNA-peptide complex using NAMD in water
sphere.
Till now I am successful in doing the simulation of both separately in
different files.
I docked them using Autodock and got the pdb file.
I have created the .psf and .pdb file containing both of them using psfgen.
I have wrap it with a water sphere.
Now i tried to do the MD with out PBC.
( conf file given but i am not sure if it is correct.)
The log file is showing this error.

ETITLE: TS BOND ANGLE DIHED

INITIAL STEP: 1e-006
GRADIENT TOLERANCE: -1.#IND

sure, I am missing some parameter in the .conf file to define the angle and
VDW energy.

I am attaching .pgn and . conf file.

hope someone can help me.

thanking

chandan
