Katharine,

Here is some code to do what you want, I think. You need to create regionaldata structure variable.

This has 2 fields, label (label names, which must match the annot file label names) and data (the values you want to project).

I've included the script and the base nifti file. If you look at the script, there are setup instructions and full details of how to run it.

Hope this helps.

Best Regards, Donald McLaren

Hello,

We are attempting to compare surface area for 46 regions of interest in subjects versus controls. We've created a list of p-values for each ROI using R Studio to compare the two groups. Is there any way to visualize these p-values mapped on to the ROI's?

Thanks very much,
