Dear Users,

I prepared the psf and corresponding pdb using vmd, but it gave error :
UNABLE TO FIND DIHEDRAL PARAMETERS FOR O C NR3 HCL (ATOMS 7422 7421 7427
7448)

I googled the error and found somewhere that deleting the cross-terms in
psf can make job to run. I did and job is running now. However, I am
curious to know whether to delete cross-terms in psf is correct or not.
Please suggest me.
Thanks in advance.
