Dear List,
I am trying to show my results on Caret's F99 atlas, in Caret. For this I already managed to take my anatomical (white, pial etc) surfaces and register them to F99 in Caret, which works fine. I am trying now to get my functional p-map (initially a nifti volume) into Caret too to overlay them on my anatomical surface together with the atlas information. For this my plan s the followign 1-Convert my nifti p-map volume into a surface using mri_vol2surf 2-Convert the resulting surface into caret surface using caret_command tools. 3-Apply to the resulting surface the same transformation I applied to my anatomical surfaces to have them all in register with Caret's F99 atlas.
It seems like step 1 works fine, but when I try to run step too, Caret complains that my anatomical surface doesn't have the same number of vertices as my functional surface. Indeed, when opening the anatomical surface in maltab with read_surf, it seems to have exactly twice the number of vertices that my functional surface has (I cannot open it with read_surf for some reason but I see the number when I open it with a text editor or when I look at the output of mri_vol2surf).
Would anyone have a suggestion as to why this is the way it is and how I could have my 2 surfaces have the same number of nodes?
Thank you very much,
Pablo
