This plugin reads molecular coordinate data stored in CHARMM Cartesian Coordinate format. More information about this file format can be found at http://pekoe.chem.ukans.edu/~kuczera/Public/web/html/charmm/files/files.html#SECTION00070000000000000000.
Note that the files created by CHARMM normally carry the extention crd. Since this extension is also used by Amber 7 trajectory files, the filetype must be explicitly set to cor when opening a Cartesian Coordinate File in VMD. This extra step can be omitted by renaming the file and changing the the extension to cor.
Read-only
This plugin is used only to read files. VMD does not currently support
writing this file type.
Unused data
The Weight field, which can be used to store atom-dependent
data such as mass or charge is ignored by VMD.
ASCII format
This plugin reads only ASCII, or "formatted" COOR files. Binary
coordinated files produced by CHARMM are presently not supported by VMD.
