Dear FSL,
I ran a two-way anova across 10 subjects and noticed that all three of my
zfstat.nii.gz files have a strange, fairly regular, speckling of negative activation
across the whole brain and also going slightly off the brain. This is is in all the
zfstat files for the f-tests, but is not present in the my normal zstat images that
are outputted from the same analysis.
Does anyone know what this speckling pattern could be from and how to get rid
of it?
Thank you!
Mengfei
