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!!

Z means Fisher's r-to-z transformation.
ROI signal analysis
Hello,
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,
