Overlapping of two brain mappings

Hi AFNI experts,

Is there any way in AFNI/SUMA to visualize the overlapping of two brain mappings? One-color brain mapping represents one condition, similar to the figure in the attachment.

Thanks in advance,
Dan

For surfaces like the ones you’ve shown, SUMA shows these kinds of images in a similar way. Each surface is colored by a dataset, usually in a niml.dset or .gii format. That dataset can be colored with different color scales and with different transparencies.

Hi, Dan-

To add a bit to Daniel’s description-- there are videos describing how to do this which will be added to the AFNI Academy YouTube channel (https://www.youtube.com/channel/UC40RiNZN7_dCuB6Lg7HJl1g) shortly.

At the moment, you can download them (the *.flv file videos play in “vlc”, and hopefully in any other software you are using to watch) and the links for the videos are here:

… showing the GUI-clicking way of doing that (recommended to start):

… and the “driving” way of doing it (from the command line), once that makes sense:
