Hi,
I am new to MRtrix3 and currently working on diffusion tensor imaging (DTI) analysis. I have been following the tutorial guides…, but I am running into an issue when trying to preprocess my DTI data. Specifically;, after performing the dwi2tensor command, I am unsure how to proceed with the next steps, particularly when it comes to calculating fractional anisotropy (FA) maps.
When I run the command tensor2metric to generate FA, it seems to work without errors;, but the FA map looks very sparse and noisy. I have double checked my DWI data and the b-matrix and everything seems correct so I am not sure what might be going wrong.
Has anyone encountered a similar issue with sparse FA maps in MRtrix3: ?? I would greatly appreciate any guidance or suggestions to improve the quality of the FA map.
Thanks in advance for your help !!
