The saved region can only be the entire region currently available, or a subset of it. The user is then prompted for file names for each saved file. Useful if one wants to start over and recreate a mask for a specific section, if not happy with the original choice. Also, if the system is very busy, occasionally switching from an open textport back to interactive mode can leave remnants of the textport on the screen. This option can then be used to correct the display.
Numbers start from zero and are automatically incremented each time an image is saved.
Up to 100 images can be made in any job. This function is only operational in the SGI version. Each masked grid point is displayed as a colored dot superimposed on the contoured section. Points outside molecular envelopes, but related to those within molecular envelopes by crystal symmetry are shown in green. Will prompt the user for the standard parameter file specifying the symmetry information.
