Hello!

Is there a way to save a cluster of interest as a mask to then use for extraction of first level betas? I’ve seen the option for drawing, but it seems it just draws masks as spheres and I’d like to save the mask in the way the original cluster looks. Also, in the case of a big cluster, is there a way to break it up into multiple regions when wanting to create masks?

Thank you so much in advance for your help!!

You can use Matlab or Python scripts for this, or use fslmaths. This is beyond the scope of MRIcroGL.
