Configuring an olfactory condition
Navigate to the Add / edit valve tab to add an olfactory stimulus. As defined in the prerequisites, a
stimulus in this paradigm will be six seconds long, followed by a 30 second odorless block. The base unit
of each input block is in milliseconds. Thus, in the duration of the
valve open period is set to 6000 and
the valve close duration is set to 30000 (Figure 39).

The paradigm already contains a predefined device with six possible stimulus channels. If the user were
to connect an ETT Olfactometer C or similar device with more possible channels this number will
automatically adjust.
Valve 1 is already preselected as the active channel. To the right of this tab, select
the Group settings tab. The empty paradigm already contains a pre-defined empty group called Group 1
(Figure 40).

By clicking on the Add to group button in the valve configuration tab, the olfactory stimulus will be
added to the selected group (Figure 41).
