Hi Experts,
I have experienced a possible problem with sided-ness within Freesurfer. I have 2 groups which have been processed through the pipeline without error. I have used the lh.aparc and rh.aparc files to extract parcellated cortex volumes, and analysed the mean differences with SPSS.
From this I get significantly different volumes in the RIGHT fusiform gyrus (amongst others).
I then used QDEC to look at vertex based volume differences and found a large significant clusters at the LEFT fusiform gyrus, but not the RIGHT.
I'm certain I haven't mixed up the analysis. Can anyone comment on this?
Thanks........J
