Dear List,
I am working in SPM v5.958/Matlab 7.0 on Windows XP 2002
I have analyzed fMRI data from 2 groups of subjects at the 1st level using a block design. Con files were created by subtracting the control from the active condition. I would like to compare the 2 groups in a 2nd level analysis using a two-sample t-test, however, the groups reaction time data are significantly different in both the control and active conditions. How can I control for these differences?
Thank-you for your help- Julie
