# mia-2dmyocard-icaseries(1)

Run an ICA analysis on a series of 2D images

## 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); string

  input perfusion data set

- \-r --references=(output); string

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

- \-c --save-cropped=(output); string

  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=(output); string

  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:

  *trace* ‐ Function call trace

  *debug* ‐ Debug output

  *info* ‐ Low level messages

  *message* ‐ Normal messages

  *warning* ‐ Warnings

  *fail* ‐ Report test failures

  *error* ‐ Report errors

  *fatal* ‐ Report only fatal errors

- \--copyright

  print copyright information

- \-h --help

  print this help

- \-? --usage

  print a short help

- \--version

  print the version number and exit

### ICA

- \--fastica=internal

  FastICA implementationto be used\
    For supported plugins see PLUGINS:fastica/implementation

- \-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-feature* ‐ difference of the feature images

  *delta-peak* ‐ difference of the peak enhancement images

  *features* ‐ 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).

## PLUGINS: fastica/implementation

- **internal**

  This is the MIA implementation of the FastICA algorithm.

(no parameters)

- **itpp**

  This is the IT++ implementation of the FastICA algorithm.

(no parameters)

## 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
