Regarding the -mprage tag, we read in the recon-all help that:
-mprage : assume scan parameters are MGH MP-RAGE protocol
-washu_mprage : assume scan parameters are Wash.U. MP-RAGE protocol.
both mprage flags affect mri_normalize and mri_segment,
and assumes a darker gm
Would you recommend using -mprage for any MP-RAGE or just if you use the
same protocol by Andre (that appears in the fs wiki and his website) ?
We are using a standard MP-RAGE sequence (not multiecho) with very similar
parameters to the ones recommended by Andre, but not exactly the same.
Many thanks!,
