rmat2pdb
rmat2pdb is a program which reads an
rmat file and creates two pdb files.
These pdb files can be used to display reciprocol lattices on top
of reciprocal density maps as explained in the
from images to density map procedure.
- The program reads name.rmat
- You set
- thmax
The maximum resolution
- lambda
The wavelength
- scale
The scale factor used by
img2r to create the density map.
These parameters can be set by loading the
mapname.rmc file, created by
img2r, using the syntax
@mapname.
- The reciprocal orientation matrix rmat is
multiplied by scale
- Creates name-axes.pdb
Generate hkl vectors along
a*, b* and c* upto the resolution set
by thmax.
Calculate the c-vector in the laboratory system:
c = rmat*hkl
Write ATOM records for the c-vectors.
- Creates name-hkl.pdb
Generate hkl vectors from -hmax to hmax, -kmax to kmax.
-lmax to lmax.
Calculate the c-vector in the laboratory system:
c = rmat*hkl
Write ATOM records for the c-vectors.
- Creates name.scm
This script can be used to load both
pdb files into coot.
