Module Description
The Qdec Module provides support for the QDEC program from MGH: Query, Design, Estimate, Contrast.
Usage
Examples, Use Cases & Tutorials
- This module is useful for visualising the output of FreeSurfer's GLM processing

- Presentation from 2007
Quick Tour of Features and Use
Before you start: Set up a subjects directory and set your SUBJECTS_DIR environment variable (you'll need to restart Slicer3). In that directory, put the set of subjects you wish to analyse, along with the fsaverage subject. Then make a subdirectory qdec, and in it place your qdec.table.dat file along with any .level files describing the discrete factors (ie gender.levels will have 'male' and 'female' on two separate lines).
You can also load precomputed .qdec archives using the 'Load Results Data File' button. This requires unzip and rm, and you can point Slicer to these applications via the Application Settings interface (View->Application Settings).
Once the results are loaded, you can plot results at various vertices by setting the setting the 3DViewer mouse mode to 'pick' using the toolbar button.

Development
Dependencies
The QDEC library (included with Slicer3) is required for this module. FreeSurfer is required for this module's use in calculating new GLM results, but is not necessary for loading pre computed ones.
