There are a couple of things you can do. To get info on the coordinate systems, look at the power points slides we have on the wiki (search for coordinates). The other thing you can do is to sample your functional data onto the surface and then load that into matlab. Then each anatomical vertex will have a corresponding functional data point and you don't need to do the transform yourself.

Hi everyone,

A sort of continuation of an old topic: I am able to load data into matlab (actually, I now plot the patches in Matlab, in order to be able to control the color myself, works great), but now I want to be able to get the x, y, z coordinates of the original data back. For example, if my functional was 64 x 64 x 18, I want to know the mapping from that space to my flattened/inflated brain.

The reason I want to know this is because I have some additional info per voxel, which I want to be able to show/pop up if I click at a spot in the flattened/inflated representation.

So, I have all the files already in matlab, now I just need to know how this conversion works. Specifying -noreshape apparently isn't the entire story.

Thanks a lot in advance,

  kind regards,

              Frank
