Dear TBSS users,
I have been running the TBSS scripts. I have obtained good (and
significant ;-))results.
I was just wondering: Can I perform a two-sample unpaired t test with age
as covariate?
Also, in the article of Smits et al. (2006) in Neuroimage, they have
mentioned several examples, where they
perform correlations within one group, using permutation-based inference on
cluster
size. How can I perform such kind of analyses? I expect they use the FEAT
toolbox within
FSL (before running randomise, creating design.con/.mat files).
Specifically: I want to perform the following analyses:
- a two sample unpaired t test (controls vs patients) with age as covariate
- a correlation between behavioral test results and FA for the two groups
(cons and pats)
- a correlation between behavioral measures and FA within a group
Best regards,
Karen
