I have been trying to run fixel based analysis based on the instructions ([Fibre density and cross-section - Multi-tissue CSD — MRtrix 3.0 documentation ])
I get one question, I do not know the meaning of the files in the stats_fd folder. I need your help.
Given the question has come up a number of times, I did at some point commence writing a new dedicated page for the software documentation, explaining the content of each of these files. However I think this was near the commencement of one of our lockdowns here in Melbourne, and I’ve thus far been unable to locate the work I’d previously invested into this I’ll try to restart that effort at some stage. Answering that general question here would not take any less effort than writing said documentation; so I’ll restrict my answer to saying that finding fixels where the value of
fwe_1mpvalue.mif is greater than 0.95 is the primary outcome of statistical inference at an alpha value of 0.05 with FWE correction.
