Dear all
I am triying to create a psf file for protein(620 residues) that is created via homology modelling. I was using the following commands
package require psfgen
topology top_all27_prot_lipid.inp
pdbalias residue HIS HSE
pdbalias atom ILE CD1 CD
pdbalias atom SER HG HG1
pdbalias atom CYS HG HG1
pdbalias atom ILE 1HD1 HD1
pdbalias atom ILE 2HD1 HD1
pdbalias atom ILE 3HD1 HD1
pdbalias atom HIS HD1 HE2
segment P1 {pdb HDKL.pdb}
coordpdb HDKL.pdb P1
guesscoord
writepdb HDKL_B.pdb
writepsf HDKL_B.psf
when executing this script psf file occurs but I got this message:
CHARMM22 All-Hydrogen Topology File for Proteins and Lipids <<
