Hi, well it
seems that the "make_restraints" command does output the connectivities I am
interested in. I just ran the default "make_restraints" with the only change
being in restraints type from "bond" to "stereo". and it does generated all
the bonds, bends, dihedrals and impropers. But I still have some doubts
:This is how my top file looks like:
# Example for: MAKE_RESTRAINTS,
SPLINE_RESTRAINTS, WRITE_RESTRAINTS
# This will compare energies of bond
length restraints expressed # by harmonic potential and by cubic
spline.
MAKE_RESTRAINTS RESTRAINT_TYPE =
'stereo' WRITE_RESTRAINTS FILE = '1fas-1.rsr' ENERGY DYNAMIC_SPHERE =
off ENERGY OUTPUT ='VERY LONG' SPLINE_RESTRAINTS SPLINE_RANGE = 5.0,
SPLINE_DX = 0.005, SPLINE_SELECT = 3
1 1 CONDENSE_RESTRAINTS WRITE_RESTRAINTS FILE =
'1fas-2.rsr' ENERGY
Now my questions, things I still need to figure
out: (1): In this case we used the 1fas.atm file as the input. What if I
donot have the pdb file available. What if the only information I have to
start with is just the amino acid sequence of the protein. So please let me
know what changes I need to make in my make_restraints.top file so that it
can read in just the sequence and generate connectivities.
(2) I
tried making an input file in the PIR format, but it does not work, this top
program looks for .pdb or .ent or .atm files only.
(3) I am not very sure
if I need to have that " CONDENSE_RESTRAINTS" and ther "SPLINE_RESTRAINTS
commands . (4) If my input file is in the form of one letter amino acid code,
and if somehow you help me make it work, how do we take care of patching the
NTER and the CTER end. (5) That ENERGY OUTPUT ='VERY LONG' that u
suggested, I am not sure what it does.
Thanks a lot for your help so
far..
Nitin
