MNI to native space

Hi,

What is the most accurate way to transform an MNI coordinate back into the subjects’ native space? Aside from linear transformation, how can I take the nonlinearity into account?
Thanks

Hi,

FSL has a comprehensive command line tool called std2imgcoord to do those kind of conversions, but you would need the warp file to do the calculation (preferentially the non-linear transformation, although I think it also accepts linear transformations, but the results will not be that good).

If you want to take the nonlinearity into account, you would need to combine the nonlinearity warp file and the MNI to subject transformation file and use the result as the warp file in std2imgcoord.

Sorry if this is not the answer you were looking for.

Cheers

Wonderful. That is exactly what I was looking for.

Thanks a lot.
