FreeSurfer experts,

I am attempting to resample HCP data into FreeSurfer space with the following how to document: https://wiki.humanconnectome. org/display/PublicData/HCP+Users+FAQ. https://wiki.humanconnectome.org/display/PublicData/HCP+Users+FAQ I believe I have resampled the GIFTI file into fs_average space, however I am running to problems visualizing it in freeview or tksurfer. Please see the error message in the forwarded message below?

Hi Tim,

Thank you for taking a look at my script, I really appreciate it. I am now running into another problem. After re-sampling into fs_average space I am attempting to visualize that file as an overlay in tksurfer or freeview (freesurfer visualization tools) however I receive the following error: *mriseadGIFTIfile: mris is NULL! found when parsing file rh.43242.32k_TJH_fsavg.func.gii*. I know that freesurfer can handle GIFTI file so that is not the problem. I wonder if the GIFTI file was created incorrectly...

Any advice?
