Hi HCP people, In the group-ICA results (the ICA parcellations), there is a volumetric MN152 3D version of the ICA maps released as a Nifti file (melodic_IC_sum.nii). Each of the volumes/series in the Nifti file corresponds to a separate ICA map. When looking at the different volumes/series in the Nifti file (which are really just the 3D projections of the surface or cortical ribbon) you can see that many areas of the surface have non-zero values. The example PNG files showing the ICA maps projected onto an axial slice are a very handy summary but they show much more discrete ICA activity compared to the raw Nifti images. Were the ICA maps thresholded in some fashion in order to generate the summary PNG files? What threshold (if any) was applied?
Thanks.
