There is a wb_command function that does this, wb_command -cifti-smoothing. We don't recommend smoothing as a general preprocessing practice however.

Do you guys know by any chance a good way to project the surface data contained in the cifti-files into a flat 2D map given in the flat gifti files? (I am trying to get the cifti data into a 2D matrix so I can convolve with a Gaussian kernel).

The reason that scene is there is simply to display the concept of BOLD fluctuations in an fMRI time series-- it is not the really meant to be data that you use any analysis tools on since we have since released several improved versions of the fMRI data on now over 800 subjects. The Group Average Workbench dataset available in ConnectomeDB<https://db.humanconnectome.org/data/projects/HCP_900> is up to date with data from the current 900 Subjects Release (of December 2015) Yes, there is extensive documentation on the many individual subject and group average analyzed data currently available for download in ConnectomeDB in the 900 Subjects Reference Manual<https://www.humanconnectome.org/documentation/S900/HCP_S900_Release_Reference_Manual.pdf> (you can also get to it in the Documentation section of the HCP public website) and more info in the publication references therein. It's a long document, but there's a lot of valuable information there.

I think someone might have spatially smoothed this raw signal and then added it to the tutorial data?

It looks like there has been some preprocessing done to the rsfMRI dtseries but I am not sure what it is. My own analysis techniques seem to work pretty well on this processed data but perform pretty poorly on the raw data. Is there any documentation/paper you could direct me to?
