5 # FILE: create_midP-2.0.sh
6 # AUTHOR: RĂ´mulo Pinho 05/08/2011
8 # Version 2.0 of the create_midP_masks.sh script. The most relevant changes are:
9 # * creation of bands around input and output image regions to try to improve
10 # the registration along lung boundaries (naturally, it depends on the quality
11 # of motion mask generation).
12 # * some steps are now in different modules, to facilitate re-use (see "includes" section).
13 # * minor modifications on output file names.
14 # * attempt to simplify the code a bit.
