This pertains to the workshop in Zurich. I am pasting this here as placeholder.

Verder zijn de triggers niet altijd in het formaat 'S 1' maar kunnen arbitrair zijn ('DIN1' had iemand hier), dat geeft ook een error (maar heb ik gefixt uiteraard). Als we weer terugzijn zal ik de trialfun aanpassen aan wat we hier hebben getweakt.

(In reply to Robert Oostenveld from comment #0) the handling of vhdr/vmrk/XXX with xxx=dat/seg and now also txt is implemented in utilities/private/dataset2files.m which is called by ft_checkconfig and by ft_read_xxx. That is easy to extend, except that it is not trivial to see what happens if you start with cfg.dataset='filename.txt'. Probably that also involves ft_filetype. I won't change it without having a proper test script. We could hand-craft some small data files for that.

for reference, this also relates to r9243 enhancement - added a trialfunction for segmented brainvision data, as requested by Eelke for the Zurich workshop
