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:
fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. fNIR optical imaging technology measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources […]
BIOPAC co-founder and R&D Director, Alan Macy, was interviewed recently by Roger Durling for the Santa Barbara Independent. The article, “The S.B. Questionnaire: Alan Macy,” provided a background excerpt of the Santa Barbara entrepreneurs’ past as well as his answers to the Proust Questionnaire. The biomedical technology developed at BIOPAC reflects an ambitious understanding of the natural and […]
Physiological researchers have been studying the lower body through examining impacts of training, movement instruction, and innovative research measurements on an individual’s well being. The following articles represent recent developments in physiological research, moving our understanding of lower limbs and the body as a whole forward, one step at a time. The Importance of Form Improper […]
