Hi everybody
After some time...I finally succeeded in using visionegg for fmri-experiments.
(i) the presentation is synchronized with the scanner (using the TTL signal
coming from the scanner)
(ii) the presentation is synchronized with the vertical retrace signal
(iii) the response of the subject, using a button box is logged via the
parallel-port
(iv) stimulus, onset-time of the stimulus, response and reaction-time of the
subject incl. potential
imprecision is logged into a text-file for easy analysis afterward
(iv) the app is running under LINUX with max_priority, so we have an excellent
timing
Congratulation, Andrew!
