Hi,
I am trying to use mkanalysis-sess in version 5.1 with 5 external regressors. I have prepared them as individual text files.

When I run mkanalysis-sess
-force
-notask
-a lot of other stuff
-taskreg seed1 1
-taskreg seed2 1
-taskreg seed3 1
-taskreg seed4 1
-taskreg seed5 1
-nuisreg global.waveform.dat 1
-mcextreg

followed by slxavg3-sess, I only get contrasts for seeds 1-4. Seed 5 is apparently not in the design matrix.
Is there a limit to the number of external regressors?
I guess I could circumvent this by having one text file with all five regressors, correct?
Thanks,
Caspar
