How do I ...
Easiest way to modify Def files is through the Def file
editor. Look for icon against def file name on
BART. This will lead you to the interface where you can edit different
parameters on def file.
Open def file editor then go to "Buttons" tab (Don't know
how to bring up def file editor ? see FAQ above). This interface lets
you choose different parameters for button like its position
(xlocation,ylocation), size(xsize, ysize) along with Text to be
displayed on button face, font to be applied to write text. You can
also put a picture on button face.
You may run simple calibration or chirp calibration. For
simple calibration look for icon. You may also use top
menu, click Calibration and then choose Simple Calibration. For Chirp
calibration click icon. You may also use top menu,
click Calibration and then choose Chirp Calibration.
First make sure your Def file is configured correctly to
run the paired comparison. Most importantly the Def file should know
where all sound
files are located. You may set sound file directory by going to
Def file editor and 'Paired Comparison' tab.
In all the programs that you run on BART, you may choose
which channel (Left, Right or Both) to use for audio output. This
setting is done at Def file editor. For eg, if you want to use only
Left channel for primary stimuli, go to Def file editor, then choose
'Primary Stimuli' tab and on Textbox labelled 'Ear' write 'Left'. This
will tell BART to use Left channel only for Primary Stimuli. Possible
values are Left, Right and Both.
