Detailed Description

Main program for stir::SSRB.

Author

Kris Thielemans & Robert Twyman

Usage:

SSRB [-t num_tangential_poss_to_trim] \
     output_filename input_projdata_name [num_segments_to_combine \
   [ num_views_to_combine [do_normalisation [max_in_segment_num_to_process ]]]]

SSRB --template template_projdata_filename output_filename input_projdata_name [do_normalisation]

Parameters

num_segments_to_combine	has to be odd. It is used as the number of segments in the original data to combine.
num_views_to_combine	has to be at least 1 (which is the default). It is used as the number of views in the original data to combine.
num_tangential_poss_to_trim	has to be smaller than the available number of tangential positions.
do_normalisation	has to be 1 (normalise the result, which is the default) or 0
max_in_segment_num_to_process	defaults to all segments
template_projdata_filename,indicated	by the –template option, a template projection data which SSRB will map to.

Example:

SSRB out in.hs 3 2

If in.hs is a file without axial compression (span=1) nor mashing, then the output would correspond to a span=3 file with mashing factor 2, and would be normalised (at least as far as SSRB concerns). num_segments_to_combine=3 results in ring differences -1,0,1 to be combined all into segment 0, etc.

SSRB --template template_sino.hs out in.hs 1

This use SSRB to convert in.hs into the shape of template_sino.hs and save the result as interile out.
