If Include header is checked the following information will be included in the beginning
of the file: file path, sample rate, number of channels, name of each channel as well as
measurement units for each channel, etc.
If Selected section only is checked then only the data currently highlighted (with the I-beam
tool) will be exported.
If Horizontal scale values is selected then time values will be included as the first column
of the resulting 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.
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:
Easily record great ECG data and derived signals for heart rate, RR interval, and R-wave amplitude. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact. AcqKnowledge Smart […]
Recent Studies using BIOPACs MP-Series (MP160, MP150) data recorders, ECG Amplifiers, and BioNomadix Wireless recorders: Singing style to infants Mothers around the world sing to infants, presumably to regulate their mood and arousal. Lullabies and playsongs differ stylistically and have distinctive goals. Mothers sing lullabies to soothe and calm infants, and playsongs to engage and […]
Alex Dimov, BIOPAC Sales Executive, was interviewed at the Neuromarketing World Forum by Inside Marketing to discuss how virtual reality can improve marketing research. Alex explains how VR can be used to present virtual iterations of a product to save time and money, and notes that measuring physiological responses adds lots of information for product and messaging […]
