Extract fALFF,Reho from SPM preprocessed NifTi files

Hi guys.

Im trying to extract fALFF,Reho from SPM12 preprocessed files.

I googled almost everywhere to find solution but I still haven’t.

Thanks to Neurostars, some of you gave me solution saying that I should use xcp_d for that.

is it ok if I use XCP_D for SPM preprocessed file? it seems like that I should apply XCP_D when I do preprocessing using fmriprep only.

Please tell me if you have solution regarding this question.

Thanks.
