Hi
I am interested in using the PLS to test the functional connectivity of certain brain regions during different task conditions. Specifically, I have two working memory tasks with different load, and how the % signal change in certain ROIs correlate differently during different task conditions, and if the % signal change correlate to demographic variables like age, IQ, or other performance data like hit rate and reaction time.
My major question is: I have already processed my data in Free Surfer / FS-FAST analysis stream, and I have already the mean% signal change of each ROI for each subject. How do I apply the PLS method or your software to investigate the above questions? I notice that SAS also has PLS function, so is it valid to use commercial software to do the analysis?
I really appreciate your kindly help!!! Have a great day too!
Cheers
