Hi,

I am considering using Vizard with fMRI. Is there a plugin available to synchronize with the fMRI volume acquisitions?

I also use data acquisition cards from National Instruments. I think I could use VRPN, but is there a native plugin for NI-DAQmx?

Thanks

hi,
you can use the SerialPort_win.py module (this is a python module and not a vizard plugin) and a timer in vizard to perpetually listen for data coming through the serial port to monitor the mri triggers. If you write the time of each trigger to a file it will match with your volume acquisitions. I have several vizard scripts that I have used (and currently using) with the fmri so let me know if you have any more questions.

Best,
Masaki
