TOLERABLY OBSESSIVE REGISTRATION AND TENSOR OPTIMIZATION INDOLENT SOFTWARE ENSEMBLE
What is TORTOISE?
The TORTOISE software package is used for processing diffusion MRI data. It contains four main modules:
DIFF PREP is used for image resampling, motion, eddy current distortion, and EPI distortion correction using a structural image as target, and for rigid body re-orientation of single subject data to a common space.
DR BUDDI is used for EPI distortion correction using pairs of diffusion data sets acquired with opposite phase encoding (blip-up blip-down acquisitions).
DIFF CALC software is used for tensor fitting, error analysis, directionally encoded color map visualization and ROI analysis
DR TAMAS (Diffeomorphic Registration for Tensor Accurate alignMent of Anatomical Structures) is a novel framework for inter-subject registration and template creation from Diffusion Tensor Imaging (DTI) data sets.

EXTERNAL SOFTWARE SOURCES
We have made use of the following external software sources, and would like to thank their creators. Masking in TORTOISE uses the bet2 algorithm from the FMRIB group, available in FSL. The non-linear tensor fitting algorithm uses the mpfit routine from the Markwardt IDL library, written by Craig Markwardt. The ImportDICOM routine is based on dcm2niix from Chris Rorden.
