Dear FSL experts,
I try to do partial volume correction for ASL data in fsl. When I put the GW/WM ratios 4D images into the Glm to design matrix, there is an error report '#5 out of bound ... RBG ...'. I also try the GM images, got the same error report.
Which one should I use, GM/WM ratios or just GM? Do I need demean the image?
Otherwise, is there any other methods to do partial volume correction, covariates with age and gender at the same time?
Thanks a lot!
