Re: [caret-users] projecting functional MRI to gii surfaces

Maybe I do some wrong things. I used the Freesurfer_to_fs_LR Pipeline to get 164k fs_LR surface. Then, I want to get the points in 164k fs_LR surface and use these points as seed to analysis the resting state functional connectivity. So I do project functional MRI to surface. But after that,

You can do that, but I am not used to seeing this done with the mean midthickness surface. Alex Cohen did something like this when he was using resting state functional connectivity to find gradients in a subject's cortical networks. He used the PALS flat or spherical map to get a common grid

Thank you for your help. Another problem is how to use the Caret software to generate  regularly spaced Cartesian grids on the flattened PALS-B12 average surface of the left and right hemispheres.  Can I use this 3-dimensional (3D) stereotactic coordinates from the PALS-B12 average fiducial (mi

Yesterday, I ran into two arcane issues worth passing on, one of which was covered in an earlier thread: 1. First I tried mapping a paint volume onto an atlas surface, but it turned out the volume was scalar values -- not discrete integers as I'd expected for a label/ROI volume. Caret generat

I'm not clear on what you mean by "I want get fMRI time course for surface vertices of every subject." If you just mean how do you scale up -- map that many volumes to all your subjects -- then I recommend scripting it and using caret_command. (Note that Workbench, the software that is superse
