Hi,
I am comparing two motion correction methods for concatenated functional data (something I have
to do, because conditions to be contrasted are not always in the same run).
The methods are:
a) simply concatenating the functional data anf then using mcflirt.
b) first using mcflirt for seperate runs, then using mclirt to register each run`s example_func to the
global example_func, and finally concatenating the two MAT_... files to register each volume on the
global example_func.
I have two questions in this context.
Does the second, rather complicated method make any sense to you, or should the results be the
same as for the first, simpler method?
Can one combine the transformation paramteres (from the xz.par files ) by simply adding them?
Cheers, guido
