2.10 Operating CinePlex Studio with RASPUTIN Sort Client
Setting up CinePlex Studio to Transmit Tracking Data to a MAP
When tracking is operational, the (X,Y) location values for up to three tracked
objects from Camera 1 (or File 1) can be time stamped and sent to the MAP
circular buffer in real time. The values are tagged as strobed data, since they
are strobed by the video frame trigger. Once in the buffer, they are available to
client software, whether written by Plexon or its customers. If enabled, the
Plexon Sort Client program displays hash marks representing the receipt of
each packet of location values. All location data values are saved into PLX
files, together with the associated neural data.
Note:
Once an initial offset message has been received after a boot, mode
change, or settings reload, data is sent to the circular buffer at all
times except when in armed state.
1 Set up CinePlex Studio so that contours, LEDs, or colors are being tracked
successfully, at least on Source 1. (This is described in detail in earlier
sections of this chapter).
2 On the Tracking 1 window, press the PLX button next to the object or color to
send to the MAP. In the case of LED or Color Markers mode, up to three
colors may be selected.
3 Press the start icon on Sort Client, and then press the stop icon a few
seconds later. This causes Sort Client to send a synchronizing time message
to CinePlex Studio so that the time stamps of neural data and video data are
synchronized.
4 Verify that strobed data is being received by Sort Client (see below).
5 If desired, delete the short PLX file created by Sort Client in Step 3.
Note:
Note that if CinePlex Studio is restarted, a different settings file is
loaded, or tracking mode is changed, steps 1 through 5 must be
repeated to ensure that position data is being sent and received as
desired.
All CinePlex Studio tracking data is recorded directly to the PLX files generated
by RASPUTIN Sort Client. After setting up CinePlex Studio to track animal
motion, set up Sort Client to record the tracking data. The following procedure
explains how to set up Sort Client to record tracking data.
Startup
The startup sequence is extremely important. RASPUTIN must be
started before Studio is started so that the client registration process
works properly. Otherwise, when a recording is eventually started by
RASPUTIN neither the file name string nor the recording time 0 messages
are received.
If RASPUTIN exits or is closed for any reason, it should be brought
back up, then Studio should be closed and restarted, as well.
