RE: Preprocessing
Hi Hanadi,
The Setup.Basic definitions are perfectly fine, for the Setup.conditions definitions I would define there simply 6 conditions (instead of 9), namely 'BeforeTreatment-condA', 'BeforeTreatment-condB', 'BeforeTreatment-condC', 'AfterTreatment-condA', 'AfterTreatment-condB', and 'AfterTreatment-condC', and then assign those to the corresponding sessions/scans (note that for the control group, if you only wish to compare patients vs. controls before treatment only, then simply assign only the 'BeforeTreatment*' conditions for the control group subjects and check the 'allow missing data' field to avoid CONN from complaining that the control subjects have no 'AfterTreatment' condition data; on the other hand if you want to be able to compare patients vs. controls both before and after treatment, I would assign both the 'AfterTreatment*' and 'BeforeTreatment*' conditions to the same data/sessions for these subjects)
Hope this helps
Alfonso

Hello CONN experts,
I am trying to use the CONN toolbox to analyze Task-BOLD functional connectivity analysis.
I have 12 patients, scanned under 3 conditions A, B and C; (before and after three month of treatment); and I have 12 Controls also scanned under 3 condition A, B and C.
Please tell me if I am setting up the analysis is correctly:
FOR Basic: Number of session 6 for the first 12 subjects and 3 sessions for the second 12 subjects.
Condition: I want to compare one condition versus another, So I define 9 conditions. ('Befor-treatment-CondA, Befor-treatment-CondB, Befor-treatment-CondAC'; After-Treatment-CondA, ..' and 'Control-CondA, Control-CondB, Control-CondC, ).
I'm nut sure how, if it's ok?
Thanks in advance,
