Module Description

This module is the BatchMake version of EM Segment Simple, a simplified "one-click" GUI interface for the EMSegment Command-line Executable. The interface is simple because the number of required command-line parameters is minimized, and it is flexible because any EM algorithm parameter can be modified, within the MRML scene, via the EMSegment GUI interface. The batch processing feature allows the user to run the EMSegment module on multiple patients. By defining a patient root directory and a mask to iterate through the patients, EMSegment simple will be run for each images found in the matched images.

Usage

MRML Scene = the mrml file name that contains all the parameters previously defined with EMSegment Template Builder module
Data directory = where the patients images are ( T1, T2 images ) Directory mask = to be a valid input, the patients directories located in "Data directory" must match the mask Target 1 mask = T1 image mask that must be matched inside the patients directories Target 2 mask = T2 image mask that must be matched inside the patients directories Output directory = where the results are saved

Examples, Use Cases & Tutorials

For the following file tree:

• Images
  • EMSegmentParameters.mrml
  • Atlas
    • ...
  • Patient1
    • Patient1.txt
    • Patient1-T1.mha
    • Patient1-T2.mha
  • Patient2
    • Patient2.txt
    • Patient2-T1.mha
    • Patient2-T2.mha
  • Patient3
    • Patient3.txt
    • Patient3-T1.mha
    • Patient3-T2.mha
• Results

Parameters are:
MRMLScene: "Images/EMSegmentParameters.mrml"
Data Directory: "Images"
Directory Mask: Patient*
Target 1 Mask: *T1.mha
Target 2 Mask: *T2.mha
Output directory: "Results"

Quick Tour of Features and Use

To run the module on a condor grid, open the BatchMake parameter group and choose "condor" as running mode. Make sure your data are accessible by all the condor machines.
