WebDWI-MRI data were pre-processed using the MRTrix script dwifslpreproc. Probabilistic tractography was performed using the constrained spherical deconvolution-based iFOD2 method with tckgen . To seed and restrict tractography of the SLF, estimated regions of interest (ROIs) were identified using SLANT, a method that uses deep learning to ... Webeddy is a very computationally intense application, so in order to speed things up it has been parallelised.

WebAs of the FSL 5.0.9. eddy patch, eddy will start by rigid-body registering all the b=0 and then linearly interpolate the movement parameters from those to the diffusion weighted images. If the b=0 volumes are interspersed among the diffusion images this works really well even in the presence of large subject movements. WebPython DWIFslPreProc - 2 examples found.
