Create a COORDS data set from input frames.
createcrd [<name>] [ parm <name> | parmindex <#> ]
This command creates a COORDS data set named <name> using trajectory frames that are associated with the specified topology. For example, to save frames that have been previously RMS-fit to a reference structure into a COORDS set named MyCrd you would use the input:
rms reference :1-12@CA createcrd MyCrd strip :6-8
Note that here the strip command will have no effect on the coordinates saved in MyCrd since it occurs after the createcrd command.
