Dear Experts
We have processed DWI data in two resolutions using QSIPrep version 1.0.0, which leaves the T1W and DWI data in ACPC space orientation but at their respective native dimensions.
Next, we have segmented T1W images using Freesurfer and THOMAS segmentation techniques to obtain the respective segmentation ROIs. We have obtained
Query: Can we use the Mrtrix based tckgen to generate tractograms between two ROIs with the WhiteMatter_FODs from either of the DWI data at their native resolution but providing ROIs from segmented T1W (in native T1W resolution)?
As such we were able to perform tckgen to generate tracts between two ROIs successfully. We are curious to know if the dimensions mismatch will lead to any undesired results.
Thank you
