ScannerSynch
ScannerSynch provides an interface for National Instruments PCI 6503 card used to capture all pulses (scanner synch pulse and button pulses alike).
For more information, type in MATLAB
help ScannerSynchClass
N.B.: National Instruments PCI 6503 card does not monitor pulses in the background, so you have to make sure that you wait for any pulse before it comes!
Any problems, report them to Tibor Auer.

Obtain ScannerSynch
ScannerSynch is available on all relevant PCs (StimPCs, "mimic" PC)
From your desktop PC (Windows), you can also have a copy from \\cbsu\data\Group\Imaging-Local\cbu\matlab
You can also download it from here (right-click and "Save As...")
Using ScannerSynch
Initialise
- Default. Use only if device (scanner, pulse emulator) is connected (only in StimPCs and mimic PC)!
SSO = ScannerSynchClass;- Emulations:
SSO = ScannerSynchClass(1); % emulate scanner synch pulseSSO = ScannerSynchClass(0,1); % emulate button boxSSO = ScannerSynchClass(1,1); % emulate scanner synch pulse and button box
Close
ScannerSynchClass has a destructor, which is automatically triggered if the object is deleted (e.g. clear, returning function). If you use a script, however, it does not perform any auto-clear, so you have to destroy the object manually:
SSO.delete;
Capture scanner synch pulse
- Simple case
SSO.SetSynchReadoutTime(0.5); SSO.TR = 2; % allows detecting missing pulses while SSO.SynchCount < 10 % polls 10 pulses SSO.WaitForSynch; fprintf('Pulse %d: %2.3f. Measured TR = %2.3fs\n',... SSO.SynchCount,... SSO.TimeOfLastPulse,... SSO.MeasuredTR); end
