Hi Francisco,
you are *much* better off avoiding going through analyze. Once you do
that all bets are off. Can you reprocess directly from the dicoms and see
if the left/right issue goes away?
cheers,
Bruce

Hello free Surfer communities,
I'm Francisco Robles from the Instituto Nacional de Neurología y Neurocirugía
in México City and I habe a serious boubt about Free Surfer Analysis, is a
basic one son I am kind of embarrased to ask it but is realllly important. I
really do not know if left hemisphere activation is the left one and right is
really the right activation one in FS-FAST.
I got my images from a GE MRI in dicom in a radiological view (left is right
and viceversa) and converted it to analyze in MRI-Converter. Then I gave the
analyze images the hole FreeSurfer Processing with strcutural and the same for
FS-FAST. I never changed the images, so I guess left stands as right and right
stands as left except if FS-FAST knows it was a radiological view and changed
it. My doubt comes now because the regions significantly activated according to
FS-FAST seem to contradict what I expected.
Thank you all in advance and thanks for putting this invaluable instrument for
free and the techinical support also.
