Hi all:
When I used fsl_glm to do one sample t-test with text matrix, I found it always return wrong results. After retesting it with different data, I doubt that fsl-glm will automatically add a constant regressor( the b item in the equation: Y = X*B + b+error ) to the regressors user specified(i.e. X)? So, fsl_glm can not do one sample t-test. Am I right?Thanks.
