Labchart Reader Download

Iwant to trigger EMG recording in Powerlab (LabChart software) via Labview. My project includes a Sequence Tracking Task which is already programmed in Labview, and I want to synchronise it with some physiological measurements such as EMG, heart rate and respiratory rate in LabChart. I was wondering if it is possible to trigger data recording in LabChart by starting the Sequence Tracking Task in Labview.

I would venture a guess that most Readers of this Forum know about LabVIEW, but do not know about (or have never heard of) PowerLab. Have you asked the makers of PowerLab if you can run their software from LabVIEW?

Thank you for the reply. I haven't asked the makers of Powerlab, but I'm pretty sure that it is possible to be externally triggered by another software. We have already triggered it by Brainstim, a software used for brain stimulation.

I don't understand what you mean my friend! There is no third party software. I just said that I'm pretty sure Labchart can be triggered by other software. Then, as an example, I said Labchart can be externally triggered by Transcranial Magnetic Stimulation (TMS). (I made a mistake in my previous comment writing "Brainstim"! I meant "Transcranial Magnetic Stimulation")

Hmm. Now that I know that "Brainstim" means TMS, I can say that I helped a colleague who was trying to do something (I don't know the details) either generating timing/driving pulses for a SQUID system (for humans, I believe) or measuring results from such a device (this was about a year and a half ago, and the details in my mind are fuzzy). I think he was doing the whole thing in LabVIEW -- I helped with getting some of the high-end DAQ equipment figured out (multiple timed pulse sequences, as I recall).

Anyway, LabVIEW and DAQmx (and high-end NI-DAQ hardware) made getting this project started quite easy (but then, we had people with a dozen years of LabVIEW experience working together). But we were not using PowerLab, know nothing about PowerLab, including how it interfaces with other routines (like LabVIEW) ...

I am a PhD student, and I would like to synchronize LabVIEW with another software named Labchart ( -reader) to facilitate my data collection. I am using a custom program on LabVIEW that includes a tracking task controlled by a joystick. Each trial of this tracking task is 30 sec, and my protocol consists of 10 blocks (5 trial per block). This tracking task is my behavioral task.

Labchart is used to measure the physiological markers of the subjects, including Electromyography (EMG), heart rate, and respiratory rate while doing the tracking task. My goal is to run these two software together to ba able to synch my tracking data recording and the physiological data recording.

I would like to be able to click start in LabVIEW to send out a signal to Labchart in order to start the data collection of my physiological markers such as EMG during each trial of the tracking task and then stop the data collection once the last trial is completed. My LabChart software is supplied with the PowerLab ( -cdn.adinstruments.com/product-data-cards/PL3508-DCW-15A.pdf) which is a data recording system from AD Instruments.

It took me a lot of time because I wanted to finish a new plugin manager before adding the support for this file format. The ADI SDK will be the first plugin managed with it.

The ADI reader should be downloaded and installed automatically.

Please update Brainstorm and let me know how it goes.

There might be things to fix, especially if you have files with multiple records or different sampling rates across channels. I wrote code for these cases but could not test it, so it's probably not working correctly.
