[FieldTrip] Biosemi eventtype problem

[Vitoria Piai]

Hi Ricarda, Alex, Elmeri et al.

Thanks. The files I'm trying to read are .bdf.
Ricarda, could you please clarify "I just recoded the markers."? Did you 
edit the .bdf file with a text editor?

In a previous dataset I acquired with Biosemi (in combination with 
Presentation), with eventtype 'STATUS', I get the right event values in 
the right number (that is, I send 10 times marker '1', ft_definetrial 
finds 10 times marker '1').
With this new Biosemi dataset (programmed by someone else in E-prime, 
it's not my data):
cfg=[];
cfg.dataset = dataset;
cfg.trialdef.eventtype = 'STATUS';
cfg.trialdef.eventvalue = '?';
ft_definetrial returns markers that were not sent, and doesn't return 
markers that were sent. (The same occurs if I read the data in EEGlab by 
the way).
It doesn't look like there's a linear transformation between what was 
sent and what FT finds. For example, markers sent were 1:21; FT returns 
[3:23 29:31], but I'll definitely look into the suggestion that maybe 
1:21 was sent but for some reason recorded as 3:23 and the 29:31 are 
coming from somewhere else.

Thanks a lot!
