Hi,
I just wanted to ask again regarding my question below.
I've noticed that 2 of the centres contribute a smaller number of subjects and don't in fact have any female controls. Should I remove these as classes (ie. take out control_Female_centre1 and control_Female_centre2) and then change the subsequent contrast file to look like: 1 1 1 1 1 1 1 1 1 1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 0 Or would this be a problem since now the number of classes that are controls or patients are uneven (10 vs. 12)?
Thanks again,
Colleen
