rmsd
C program for calculating rmsd from a charmm DCD file.
Dependencies
Lapack and Blas are required for compiling this software.
How to run
Please provide 4 arguments to the program:
- path to CHARMM dcd file (binary)
- path to reference structure (CHARMM .cor text file)
- atoms selection for rmsd (command line)
- atoms selection for centering (command line)
Note that it is not necessary to use 2 identical selections for centering and rmsd
For a selection by residue name (3rd column of CHARRMM .cor file): ./rmsd *.dcd *.cor rmsd=resname:GLY,LEU center=resname:GLY,LEU
For a selection by atom name (4th column of CHARRMM .cor file) : ./rmsd *.dcd *.cor rmsd=atname:C,CA,N center=atname:C,CA,N
For a selection by residue number (2nd column of CHARMM .cor file) : ./rmsd *.dcd *.cor rmsd=resnum:15,19,62,101 center=resnum:15,19,63
For a selection by atom number (1st column of CHARMM .cor file) : ./rmsd *.dcd *.cor rmsd=atnum:1114,1123,1169,2056,6987 center=atname:C,CA,N
