protein structure file (psf)- III



Hi,
This is what I generated from CHARMM for the NMA dimer. How can I generate
the same information using Modeller. The suggested "write data" command
gives me the numerical values for the dihedral angles. But I am interested
in the connectivities based on the atom indices....

Dear Nitin,

Please check out these commands:

WRITE_MODEL
This command writes the current MODEL to a file in the selected format. If
the file format is 'PDB', only the selected atoms are written out when
WRITE_ALL_ATOMS = off; otherwise all atoms are written out.
http://salilab.org/modeller/manual/node65.html

especially this one:
WRITE_DATA
This command writes the selected types of data about the MODEL to a
corresponding file.
http://salilab.org/modeller/manual/node79.html

WRITE_TOPOLOGY_MODEL
This command writes a residue topology library to the specified file.
http://salilab.org/modeller/manual/node61.html

WRITE_PDB_XREF
This command writes the correspondence between the PDB residue numbers and
residue indices for the selected part of the MODEL.
http://salilab.org/modeller/manual/node80.html

Thank you,
Bozidar

Hi,
I am a new MODELLER user. I am interested in generating a structure file of
the protein of my interest.I was wondering, if there is a way in MODELLER to
write down a "CHARMM like .psf " file that lists all the bonds, bends,
dihedrals, improper dihedrals etc ( for an all atom model, including
hydrgens). Supposedly, the "BUILD MODEL" only generates the 3 D coordinates
of the atoms in the model, based on the specified sequence of amino acid and
the CHARMM topology and parameter file. But I can not figure out how to
output a psf, structure file of my model protein.

Looking for some help,
Thanks in advance,

Nitin
