We have been this far unable to do so. We have succesfully ran Dual_regression using our own Concat-ICA derived templates, but have been uncapable of using the maps that have been kindly uploaded for the benefit of the neuroscientific community.
We hypothesized that maybe dual regression only allows templates that share the same FOV and Voxel Size that the subjects being regressed unto; if so, we imagine this same scenario has been tackled before, as many people probably have wanted to use the PNAS paper as a template and not necessarily having the same data size.
If we're correct on that asumption, is there a preferred method for resizing the subjects or the templates to get the match? We already tried using fslroi for obtaining the same FOV, but to no avail.
Thank you SO much, in advance, both for whatever light you might spark to our problem, and for your stimulating work in fMRI.
