Hi Francesca

sorry, not sure if this got answered, but you should be able to create surface-based ROIs and run the analysis on them.

Dear Bruce,  Thank you very much for answering!

We are doing a study on correlating dyslexia, at an early stage, with various factors in children. Specifically, our goal is to look at how the 12 regions of the brain, that I mentioned in the previous email, play a role in the study.

Up until now, I have done an mri_average of all the images and used the qdec interface to see how cortical thickness and surface area vary with parameters such as gender, age and maternal education. This produced interesting results but they get affected when the Monte Carlo correction is run on the same. Further, I want to run the analysis specifically inside certain regions of interest. For that purpose, I thought about creating the masks in freesurfer considering just the regions of interest and  run the analysis in them. Is this a good way to go about this?

Thank you very much for your kind attention.

Best regards,

Francesca
