The schedule tool was designed for quick edits you may want to make while testing or setting
up a new paradigm. For permanent edits to your stimulus, TDT recommends using SigGenRZ
(included with BioSigRZ installations) to modify the stimulus
fi
les (.sig) directly.
Customizing the Stimulus
SigGenRZ is a signal design software that enables you to create stimuli in a dialog box driven
environment. Most importantly, it allows most settings to be used as variables for your
experiments. All of the signals used in the BioSigRZ out-of-the- box experiment con
fi
gurations
have been created in SigGenRZ. It is also a helpful tool for modifying aspects of the stimulus
that are not editable from within BioSigRZ.
To modify a
fi
le directly in the SigGenRZ software you will need to follow these basic steps:
Open the stimulus
fi
le (.sig) in SigGenRZ.
Make changes in the
fi
le.
Save the
fi
le or save the
fi
le with a new name.
Open the desired BioSigRZ con
fi
guration
fi
le (.acf).
Load or reload the stimulus
fi
le.
Save the BioSigRZ con
fi
guration
fi
le.
Opening the File
The stimulus
fi
les (.sig) for the BioSigRZ out-of-the-box experiment con
fi
guration are stored at:
C:/TDT/BioSigRZ/SIG/
For ABRs, there is one
fi
le for click stimuli and one for tone stimuli:
Click.sig
and
TonePip.sig
,
respectively.
It is generally a good idea to leave the original
fi
les unchanged and in place, but you can still
use and modify these
fi
les then rename the
fi
le.
To open the signal
fi
le you wish to modify:
Click the
Start
button on the Windows taskbar, point to
Programs
, point to
TDT Sys 3
, and
click
SigGenRZ
.
Select
Open
from the
File
menu.
