I have seen a MRIcron bug for sagittal acquisitions. May that be the case?
Cheers-

Betreff: [FSL] FEAT seems to flip Left and Right orientation
Dear FSL community,
I have a problem in FSL where the brain image seems to flip randomly. I know fsl displays images radiologically however for some reason sometimes the images is flipped. For example when we perform left finger tapping experiments activation appears in the left hemisphere of the brain.
I was thinking it might be the way I convert the data to FSL *.nii.gz format. The images that we acquire are *.hdr *.img files which I convert to FSL compressed format using MRICRON. Maybe the raw data lacks any orientation data so fsl seems to flip it randomly?
I was wondering if there is a way to lock the right and left hemipsheres so that it doesn't flip. I used flsorient and it says the data is neurological however i've run the data several times and sometimes the image flips and sometimes it doesnt.
Thank you,
-William Sohn
