PDB CG3 - PDB - Calculate center of gravity

PURPOSE

Determine coordinates of center of gravity of atomic coordinates in a PDB file.

USAGE

.OPERATION: PDB CG3 [xcp],[ycp],[zcp], [xcs],[ycs],[zcs], [na]

[[xcp],[ycp],[zcp] will receive coordinates of the center of gravity in PDB cordinate system. <br /> [xcs],[ycs],[zcs] will receive coordinates of the center of gravity in SPIDER coordinate system with units of Angstroms. <br /> [na] will receive the total number of counted atoms. Both sets of data are printed in the results file. ]

.INPUT FILE: img.pdb
[Enter the name of the PDB file with extension.]

NOTES

1. The coordinates should be divided by pixel size if the coordinates are expected in the unit of pixel.

2. Implemented by Zhong Huang, Pawel A. Penzcek.
