I’ve tried to use FSL (5.0.9 and 6) FEAT to do an arterial spin labeling analysis. When I use the subtraction option in the pre-stats, during the stats analysis, I get the error:
fslmaths stats/correction -mul 2 stats/corrections

Has anyone encountered this before?
Does anyone know if this error is causing incorrect outputs to be generated and what is causing the problem? Does anyone have a proposed work-around or solution?
