I am trying to do some resting state analysis based on hcp.
I am following the tutorial of hcp, and got the PSD map (https://neuroimage.usc.edu/brainstorm/Tutorials/HCP-MEG).
At the individual level in tutorial, everything works perfect. But next step, when I want to project the result to default anatomy, I got the message at the matlab command window that "All values are null. Please check your input file.". And accordingly, no results are found in the group level. And I checked the output of tess_interp_tess2tess.m file, the Wmat contains only zeros (so I guess Wmat is not calculated).
Is there any possibility that I project my result to group level for group analysis?
Are you trying to reproduce the tutorial using the example dataset, or using your own recordings?
I recommend you start with the dataset distributed with the tutorial first. Let us know if there is any step that you don't manage to reproduce.
Following your group analysis tutorials, I have conducted other studies at the group surface level using brainstorm smoothly.
But now my new study needs to use hcp data set for investigating rest task interaction, and I wish to work in the surface. Everything goes well for replicating your hcp tutorial. But when I want to project the individual results to default anatomy, I failed for every subjects.
The warning message is attached here.
I guess this warning tells me that in hcp tutorial, the anatomy imported with hcp pipeline v3 does not contain freesurfer structure, and that leads to the failure in projection?
