rmat2pdb


Introduction

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.

How it works

  1. The program reads name.rmat
  2. You set These parameters can be set by loading the mapname.rmc file, created by img2r, using the syntax @mapname.
  3. The reciprocal orientation matrix rmat is multiplied by scale
  4. 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.
  5. 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.
  6. Creates name.scm
    This script can be used to load both pdb files into coot.
