Hi Stephen,

For the 1st level you would code/model the stimuli/responses that are of
interest. If I am understanding correctly, you want one for each run, test
between training vs. control, not mixing or comparing the runs, but rather,
having 3 separate tests, is this correct? If yes, then 3 separate paired
t-tests will work. If each run is considered a "modality", then these can
be corrected across with "-corrmod" in PALM.

If, however, you'd like to compare the three runs, then have a look into
the first sheet of this file: https://dl.dropboxusercontent.com/u/
2785709/outbox/mailinglist/design_karolina.ods

This design can be used in FEAT.

Hope this helps. If not, please feel free to ask again.

All the best,

Anderson
