Saving an AcqKnowledge file as a text file.
In the exported text file each column represents data from a different channel. If Horizontal scale values was selected then the first column contains the time values. Here is an example of an exported text file.
ms CH0 CH1 CH2
2 2 2
In the above example, the values should be interpreted as follows:
Blood Pressure: 87.2121333, 87.1100708
EMG: 1.010376, 1.0100708
Time: 0,10 (msec)
Importing a text file into AcqKnowledge.
1. Go to File > Open
2. From Files of type select Text file
3. Click on the Options button
The Read line option allows you to import only a section of the file
The Interval option allows you to define the sample rate
The Column delimiter allows you to specify how columns of data are separated
When importing a text file it should have the following format (the delimiter could be a comma, tab or a space):
Every row corresponds to a sample point at a given time and every column contains the data for a different channel. For the above example, if the sample rate was 1 second, the file will be interpreted as follows:
BIOPAC shows you how physiological data is seamlessly synchronized with eye tracking and stimulus presentation in one integrated solution. The talk focuses on optimizing setup, highlighting the benefits of a fully-integrated solution, and how to extract eye tracking and physiology metrics from key points, such as the cumulative average skin conductance level while a participant is focused on areas of interest.
What you will learn:
• Hardware setup
• Stimulus presentation creation
• Setting up Areas of Interest (AOI)
• Recording participant data
• Analysis and reporting
