Export / average statistical maps in source space

I've got several t maps in MNI space across participants and I was wondering if it's possible within the existing Brainstorm framework to either export them to nifti or calculate an average of the maps?

Alternatively, could I just copy the structure of a statistics file and replace the data with the averaged data?


If you want to reuse the t-values computed by the statistics functions in Brainstorm for other purposes (averaging, exporting...), call the process "Apply statistics threshold" first:

If you do not want to apply any threshold, use an uncorrected p-threshold of 1.
This will produce maps of t-values that you will be able to average across participants.

You can also export these files a .nii or .gii files:

Thanks Francois! Sorry, that tutorial seemed to pass me by.
