Thank you, Doug! Found the CSD file. Just want to make sure that I picked up the correct one: mult-comp-cor/fsaverage/lh/cortex/fwhm08/abs/th23/mc-z.csd corresponding to a FWHM=8, voxel-wise z-thr=2.3, the sign is both pos and neg? Actually, the zstats were converted from pearson correlations, which I want to see both pos and neg relationships. Another point: is the CSD file designed for fsaverage specifically? I did analysis on fsaverage5, can I just use this file or have to resample the surface to fsaverage space?
