Dear All,
A quest for rather basic advice.
I need to evaluate the quality of coregistration of pairs of
structural MRI T1 nii volumes aquired on different scanners/protocols
(n pairs = ~50), for several coregistration methods, including spm's.
So I need similarity metrics and associated statistics (eg ANOVAs
folowed by 2 group comparisons). Such comprehensive assessment would
include correlated methods, such as DARTEL run with varioud parameters
in a param search study. I assume a place to look for such similarity
measures are simply the cost functions used for coregistration methods
in spm, such as Coregister/estimate, DARTEL's etc. Which such
similarity metrics you recommend, and are they implemented in spm or
one of the associated plug-ins, again including statistics?
Looking for widely accepted standard measure(s) for the type of data
involved (see above). Thank you,
OL
