The structural results (surfaces, thickness, myelin maps) are available on a 164k mesh because the structural data was acquired at a resolution (0.7 mm) that supports such a fine grained mesh. The functional data were acquired at 2 mm resolution, which is approximately the average spacing in the 32k mesh. Plus, working with the fMRI data on a 164k mesh would require 5x the memory and storage for a dense timeseries (and 25x the memory/storage for a dense connectome).

Thank you very much!
