AcqKnowledge is software used for recording physiological data using the BIOPAC system and can be used for further physiological data processing. 

Availability, support and advice

AcqKnowledge is available for researchers at FSW Leiden and is preinstalled on all lab computers. The software can be installed on work computers through the Software Center. AcqKnowledge will also work on university laptops outside of the FSW building.

SOLO supports AcqKnowledge, although the research support team does not have experience with all its features. AcqKnowledge is mainly used for recording physiological data with BIOPAC hardware. For physiological data preprocessing/analysis, check out the PhysioData Toolbox, which provides a user-friendly interface for batch processing physiological data files.

Tips & Tricks

BIOPAC Webinars
Watch this webinar on AcqKnowledge tips and tricks. Other useful BIOPAC webinars are available here.

Help menu
The Help menu in AcqKnowledge offers quick access to manuals and tutorials.

AcqKnowledge preferences
Use the gear wheel in the AcqKnowledge toolbar to access the AcqKnowledge preferences. When you are not sure about the settings, leave them at their default, which works well for most studies.

Right click on graph
Right clicking anywhere on the graph reveals a useful menu. Options include:

  • Autoscale single waveform and Autoscale waveforms 
  • Show all data 
  • Split view
  • Channels (for hiding and showing channels)

Click on the right axis of the graph
Clicking on the axis on the right side of the graph reveals some options, including

  • Scaling options
  • Showing textual values on graph (useful for e.g. marker or heart rate channels)

Network Data Transfer
When using Network Data Transfer it needs to be enabled in the AcqKnowledge Preferences, in the Networking section. Use the gear wheel to access the AcqKnowledge Preferences.

Note that Network Data Transfer needs to be enabled for each user! It cannot be saved in a template.

Channel selection
Make sure you select different channel numbers for the to be recorded signals. When the same channel number is used for two different signals, these signals will be recorded in a distorted manner.
