I have used spm smoothing to smooth my data, setting the fwhm as an iterable using three different values for the kernel. The pipeline continues after that with masking, high pass filtering and finally with running ICA as implemented in fsl Melodic. I am quite satisfied with one output from the smoothing. Now, I want to regress bad components out of only one output of the three. I tried to use utility.select, but it works on all of the three branches.
Is there a way to continue the pipeline on only one output of the smoothing?
