Tracy,

Does your 'time' factor appear in the 'Data Table View' box? If so, then when that is selected, then the 'Selected Factor' will change to that in the 'Subject Exclusions' box, which should allow you to enter a particular values for exclusion.

Hello Surfers,

I am trying to do a qdec analysis and I am working with several hundred subjects. I have my data divided up into different time points and a discrete factor called time. I would like to look at just time 1, then time 2, then time 3.

I know how to exclude individual scans by right clicking on a scan and selecting "Exclude" in the qdec pop-up window.

What I was wondering is if I could select for exclusion all subjects at once, using the Subject Exclusions windows, that are not time 1.

Thanks,
