CSPM will run repeated measures ANOVA (RMANOVA) on fMRI timetrends and physiology if SAS is installed and setup.
VOI timetrends
Within and between group
Run the VOI timetrends from the DIsplay Results GUI. This will generate SAS subfolders for each VOI, and an extra MATLAB figure and Excel table of results:
The Excel fiel "Table of RMANOVA results" contains model fit information, and the figure "fig_RMANOVA" contains between-group and within-group time-points of difference (if any). By default the graphs are squished, so click edit plot and expand them.
Because the asterisks are lined up with the middle plot, make sure you don't drag them out of alignment.
In the ...\SAS\lib folder, the withingroup.txt and betweengroup.txt files contain the marginal means and differences, standard errors, and p values.
Within and between VOI
Once the VOI are loaded, you can select multiple VOI and Plot, and it will also create the RMANOVA files.
The RMANOVA and figure files are saved in temporary folders. There will be a link in the Command Window. If you select differences, it will do RMANOVA for differences between VOI.
SAS setup
Install SAS in your system, made sure the license is current ("setinit" file needs updating every year), and in CSPM, Options, Local settings make sure the path to the program file is set.
