Hello again,

Thanks for your quick response. In addition to my previous question, I would also like to learn what the default analysis in Qdec is actually doing.

For example, as I said previously, I have only one patient and a group of control participants. In that case, in my data table I'm giving a discrete "group" factor (patient, control) and the volume values of brain areas I'm interested in (several continuous factors). Then, I'm choosing "group" as my Selected factor (under Subject exclusions). When I say 'analyze', what the default analysis of Qdec is actually doing? Which statistics exactly? Since I have only one patient, is it computing the patient's mean as 0?

Thanks in advance,

Buse.

Hi Buse, I think this is a two-sample t-test where the 2nd sample is
your individual. You should be able to this in qdec

Hello,

I would like to learn whether we can conduct one-sample t-test using Qdec.
I'm working on a single-case study, and I want to compare a single subject's data with a group of controls (to see how this specific subject is different from the group) in terms of volume, thickness and meancurvature. As far as I know, we can do the analysis in Terminal, but I would like to see & have the brain figure output (cluster by cluster) in Qdec for one sample t-test as well. Is it possible?

Thanks in advance,

Buse.
