Dear Robert,
as I replied yesterday, trialfun_general does indeed create trials, at
least if I directly specify eventtype as a string. If I however try to
use eventvalues from the trigger channel (UPPT001 in my case) I noticed
that FT changes the values from what presentation send (and from what
BESA reads correctly) in the following way:
Stimulus CTFdisplay BESAreading FTreading
'StimUpper' 2 2 3
'StimMiddle' 3 3 5
'StimLower' 4 4 7
i.e. it changes it from the first three numbers bigger than 1 to the
first three odd numbers that are bigger than one.
Is it possible that there is still some frontpanel+backpanel binary
addition going on - even in trialfun_general?
Thank you very much for your help.
Best Regards,
Michael
