Description: This plugin calculates FA, Mean diffusivity (MD), largestest (D1), second (D2) and smallest (D3) eigen diffusivity, radial diffusivity (Rad) and color coded FA maps from DTI images.

Instructions:

Open multiple images in the 4D viewer and run the plugin.
By default, the plugin attempts to read in gradient encoding directions from DICOM fields.
Possible options include:
- "Load from DICOM fields" attempts to read in gradient encoding directions from DICOM fields.
- Using "Load from file", a gradient table can also be loaded from an external space separated .txt file, with each row containing one diffusion direction.
- Load previously saved gradient table from local database, a list of tables will be displayed for selection
- Note:The current gradient table can be saved to a local database using "Save Current Table"
- Input manually to the table
Set the noise threshold, voxels with B0 signal lower than this threshold will not be processed.
Choose what output images to produce. Sometimes, for colorFA to display correctly it may be necessary to check "Don't propagate WW/WL between series" in Menu "2D Viewer"
AutoSave: Choose whether to automatically save the output images to the database
To correct for eddy current induced distortion, Exporter plugin can be used to export/import the images to/from nifti type and interface with FSL
