Dear freesurfers,

I have data collected here at the martinos using the Siemens ep2d_PASL sequence. I run the command "rcbf-prep —s subject —rcbf asl.nii —o tesfolder" or something like that. The resulting rcbf.nii looks good, but the values are negative? Is this just a matter of tag and ref images being in a wrong order and can I just fix it by removing the first image (after the M0)? Or is it more complicated?

Thanks for your help Lauri
