How to write a 2D matrix into gii file in matlab?

[vidasun]

Hi! I used the gii.cdata matrix to perform filtering. And after that, I wondered if there's any way to write this 2D matrix into a new gii file.?I've looked at the example in tutorial and it seemed the isosurface function can only be used on 3D data. Thanks!

Hi @vidasun,
If I understand you correctly, you can use the .cdata field to store your 2D array and have it saved in a new GIfTI file, e.g.:

g = gifti;
g.cdata = rand(256,16);
save(g,'data.gii')
