DTI and DKI processing
by Maharjan, Surendra Nov. 25, 2021

Nov. 25, 2021

Hello Dipy Developers, My name is Suren. I am doing group-wise analysis of Alzheimer’s disease and healthy controls normal brain. I could successfully run DTI and DKI analysis. I did all other preprocessing steps: 1. Denoising (dwidenoise from MRtrix3) 2. Gibb’s artifact removal (from MRtrix3) 3. Eddy current correction and motion artifact removal (affine registration) Yet, I am wondering if we need data normalization and data regularization before performing DTI and DKI analysis. Also, I am wondering if we need to remove outliers before conducting both. I am using 3 shell dMRI data acquired in 9.4 Tesla MRI Scanner. I am waiting for your favorable response. Thank you very much. Best Regards, Suren Indiana University

[Dipy] Group Average Tractogram
by Eric Kirby Nov. 17, 2021

Nov. 17, 2021

Hello, How would one go about creating an average Tractogram that is a combination of all subjects’ datasets in a group? My current idea is combining all bvec and bval files, transforming all raw DTI data to standard space, merge all DTI data, then put the resulting file through my pipeline. However, this would create a massive file with a few hundred volumes. Any ideas on a better way to do this? Cheers, Eric
