Region Panel: file

NRAO Home > CASA > CASA Cookbook and User Reference Manual

7.3.5.3 Region Panel: file

The third tab ’file’ is used for loading and saving regions from and to disk (select the appropriate the action at the top). If no region has been created, the region panel will be empty. Use the regular “Load Data” file browser (§ 7.2.4) to load the a region file. To save to ascii file, one can specify the file format, where the default is a CASA region file (saved with a *.crtf suffix, see §D). It is also possible to load and save DS9 regions, but remember that the DS9 format does not offer the full flexibility and cannot capture stokes and spectral axes. DS9 regions will only be usable as annotations in the viewer, they cannot be used for data processing in other CASA tasks.

When saving regions, one can also specify whether to save only the current region, all regions that were selected with SHIFT+click, or all regions that are visible on the screen.
