This command saves the molecule model in model_number (not preceded by #) as a PDB file. Only atomic coordinates and secondary structure records are saved; atomic display status, color, and radius are not included. The write command does not work for non-molecule models (surfaces, VRML models, etc.).
The relative option specifies that the coordinates written out are relative to the untransformed coordinates of model n; otherwise, the coordinates are written as currently transformed. This option may be specified in either of two places in the command line (see usage above).
