Time series analysis and ROI signal folder

Hi all, 

So after processing and extracting roi signals, the next step is for me to analyze the roi signals of my subjects using SPSS. Does anyone know what type of analyisis I should carry out on SPSS as I have two groups, one healthy and the other  have Alzheimers.
Whic do I use rregression or corellation.

Also what does the different type of file mean in the results folder for roi extraction. does  Z mean zett?


much appreciation, really  benefiting from this program!!


You can perfrom two sample t test in SPSS.

Z means Fisher's r-to-z transformation.


In this post, Dr. Yan explains the files in the ROI extraction folder: http://wiki.rfmri.org/content/extract-roi-time-courses-roi-wise-functional-connectivity

For means comparison: As another option, if you have matched the subjects, you can use a matched-pairs (repeated measures) t-test, which has more power than a two-sample t-test. If you collected multiple runs per subject, you will need to use a mixed-effects analysis.

r-to-Z transformation is used I believe when you need to do further analysis on r, which cannot itself be manipulated arithmetically.

Do you happen to have any further information on this issue? I am conducting a very similar analysis and would like to share ideas if possible. I don't know how to get in touch with you directly, but if you're interested, my email is: flgarciaATchlaDOTuscDOTedu

All the best,


I'll ask my students to help you.
