Hi Maren,
The ANOVA: 1-factor 4-levels section of the FEAT documentation should help with this:
http://www.fmrib.ox.ac.uk/fsl/feat5/detail.html#higher
Note that you will also need to create an exchangeability-blocks file to respect the repeated-measures in your input data ( and make sure you are using the FSL 4.1.8 version of randomise, as previous versions had an issue with the exchangeability-block -e option ).
Many Regards
Matthew

I have data from a cognitive test with one factor and 4 levels. So far, I correlated difference measures between levels of that factor using the one-sample t-test with covariates, but I would like to know whether there are white matter regions that show altered FA values across the levels of the factor. Can anyone tell me whether it is possible to set up a design matrix for this or am I wasting my time?
