AcqKnowledge
Introduction
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 comes preinstalled on all lab computers (see the Software List to check which version). 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.
Markers
To analyze physiological data obtained with Biopac, markers that signal the onset of certain events need to be sent from the stimulus presentation pc to the Biopac. In order to process these markers, a marker channel needs to be created in AcqKnowledge, see Marker channel for instructions on how to add such a marker channel. See for more information on sending markers the pages Sending Markers in E-Prime and Sending Markers in OpenSesame and the Markers and Events page for more information on markers in general.
Tips & Tricks

Help menu | |
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. | |

Network Data Transfer 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. |
