It depends on what you mean with registration... I don't want to normalize the data to a standard space
(for example MNI-Template)... ... and I don't want to "wrap", "translate", whatever "manipulate" the data in this way...
maybe the other way round may be possible somewho? wrapping a V1-representation of wfu_pickatlas to my data?
