Fixel mask from results of whole brain analysis

Hello experts,

I ran a FBA and have some results for the cingulum bundle for FD. I was wondering how to create a fixel mask for the regions that were significant in the whole brain analysis, to then extract these values. Thanks very much for your guidance!

Best,
Alex

Hi Alex,

If literally all you want is “a mask of those fixels that were significant”, this is easy:

mrthreshold fwe_pvalue.mif -abs 0.95 -

or

mrcalc fwe_pvalue.mif 0.95 -gt -
