Hello, I am working with diffusion MRI data from Freesurfer and have been using MITK Diffusion to generate networks and connectivity matrices. Workflow has been to process the DTI in MITK Diffusion and with a generated mask to create a fiber bundle, then using the fiber bundle with Freesurfer labels in DTI space to generate the network and connectivity matrix.
My problem arises with the dimensions of the connectivity matrix. There is a mismatch between the dimensions of the MITK generated matrix and number of Freesurfer regions. Sometimes MITK Diffusion reports more columns than there are FS regions and other times there are fewer columns than FS regions. What is the cause behind this and is there any way to fix this?
