(Preprocessing) Process steps 1.1 -1.6 (see below) |
-bedp |
(Bedpost) Process step 2 |
-path |
(Pathway Reconstruction/Tractography) Process step 3 |
Processing Stages
prep
1.1 Image corrections - Eddy current correction with eddy_correct, B0 field map correction with epidewarp.fsl.
-corr |
to do this step (Default) |
-nocorr |
to skip this step |
1.2 Intra-Subject Registration - Diffusion-to-T1 registration with flirt and/or bbregister.
-intra |
to do this step (Default) |
-nointra |
to skip this step |
1.3 Inter-Subject Registration - T1-to-template registration using MNI and/or CVS templates.
-inter |
to do this step (Default) |
-nointer |
to skip this step |
1.4 White-matter, cortical and whole-brain masks - Generate masks of the white matter and cortex from FreeSurfer outputs, whole-brain masks from T1 and DWIs.
-masks |
to do this step (Default) |
-nomasks |
to skip this step |
1.5 Tensor fit - Tensor model fitting on DWIs.
-tensor |
to do this step (Default) |
-notensor |
to skip this step |
1.6 Pathway priors from atlas to T1 - Combine training data and subject's own data to generate pathway priors.
-prior |
to do this step (Default) |
-noprior |
to skip this step |
bedp
2. Stick and ball model fitting with bedpost (Cluster highly recommended for this step)
path
3. Pathway reconstruction - Perform tractography for a single subject
