NAME

       mia-2dmyocard-icaseries - Run an ICA analysis on a series of 2D images

SYNOPSIS

       mia-2dmyocard-icaseries -i <in-file> [options]

DESCRIPTION

       mia-2dmyocard-icaseries  This  program  is  used  to  run  a ICA on a series of myocardial
       perfusion images given in a segmentation set in order to create sythetic  references  that
       can  be  used  for  motion  correction  by image registration. If the aim is to run a full
       motion compensation then it is better run mia-2dmyoica-nonrigid,  since  this  program  is
       essentially the same without the registration bits.

OPTIONS

   File-IO
              -i --in-file=(required)
                     input perfusion data set

              -r --references=
                     File name base for the reference images. Image type and numbering scheme are
                     taken from the input images.

              -c --save-cropped=cropped.set
                     save cropped set of the original set to this file, the image files will  use
                     the stem of the name as file name base

                 --save-feature=
                     save the features images resulting from the ICA and some intermediate images
                     used for the RV-LV segmentation with the given file name base to PNG  files.
                     Also  save  the  coefficients  of  the  initial best and the final IC mixing
                     matrix.

   Help & Info
              -V --verbose=warning
                     verbosity of output, print messages of given level  and  higher  priorities.
                     Supported priorities starting at lowest level are:
                        info ‐ Low level messages
                        warning ‐ Warnings
                        error ‐ Report errors
                        fail ‐ Report test failures
                        message ‐ Normal messages
                        fatal ‐ Report only fatal errors

              -h --help
                     print this help

              -? --usage
                     print a short help

                 --version
                     print the version number and exit

   ICA
              -C --components=0
                     ICA components 0 = automatic estimation

                 --normalize
                     normalized ICs

                 --no-meanstrip
                     don't strip the mean from the mixing curves

              -s --segscale=1.4
                     segment and scale the crop box around the LV (0=no segmentation)

              -k --skip=0
                     skip images at the beginning of the series as they are of other modalities

              -m --max-ica-iter=400
                     maximum number of iterations in ICA

              -E --segmethod=features
                     Segmentation method
                        delta-peak ‐ difference of the peak enhancement images
                        features ‐ feature images
                        delta-feature ‐ difference of the feature images

   Processing
                 --threads=-1
                     Maxiumum number of threads to use for processing,This number should be lower
                     or equal to the number of logical  processor  cores  in  the  machine.  (-1:
                     automatic estimation).

EXAMPLE

       Evaluate  the  synthetic  references  from set segment.set and save them to refXXXX.??? by
       using five independend components, and skipping 2  images.  Per  default  a  bounding  box
       around  the LV will be segmented and scaled by 1.4 and the cropped images will be saved to
       cropXXXX.??? and a segmentation set cropped.set  is created. The image file  type  ???  is
       deducted from the input images in segment.set.

       mia-2dmyocard-icaseries -i segment.set -r ref -o ref -k 2 -C 5
