Dear community:
I am having trouble normalising the FOD.

mtnormalise wmfod.mif wmfod_norm.mif gmfod.mif gmfod_norm.mif csffod.mif csffod_norm.mif -mask mask.mif

[ERROR] Non-positive tissue balance factor was computed. Balance factors: nan nan nan

What could I do to proceed?

Thanks in advance!

I have seen this issue is related to this thread Mtnormalise nan values as balance factors - #16 by jdtournier

mainly because of the strange value of gm
you could delete the gmfod and try that again
