Generate and Apply Mask : Make a soft mask of the region to be excluded.
Usage in command line
sp_signalsubtract.py sp_mask --map2mask=map_to_make_mask_from --fullmap=full_map --outdir=output_subtraction_directory --mapthresh=threshold --verbosity=verbosity_level
sp_signalsubtract comprises the steps needed to subtract masked regions from a map in order to focus on the remaining features from that map. There are six steps for this process (five within SPHIRE):
2. Locate regions to be subtracted
3. Mask a soft mask of the region to be excluded :
sp_signalsubtract.py sp_mask --map2mask=map_to_make_mask_from --outdir=output_subtraction_directory --fullmap=full_map --mapthresh=threshold
The map to make a mask from (–map2mask) corresponds to the region that you want to subtract.
!!!IMPORTANT!!! The full map which is to be multiplied by the mask (–fullmap) must NOT have been postprocessed (e.g., sharpened). Otherwise, re-projections will not be optimally comparable to the experimental images.
