To duplicate a waveform, select the waveform (channel) and click “Edit > Duplicate Waveform”.
For Windows versions of AcqKnowledge older than version 4.0:
When selecting the waveform, BIOPAC recommends choosing “Edit > Select All” so that the full waveform is selected and not a partial waveform. If only a section of the waveform is highlighted, only the highlighted area of data will be duplicated.
For AcqKnowledge version 4.0 and above to mimic earlier behavior (copying only a piece of a waveform), use the I-beam tool to select the area to be duplicated, type control-c (command-c on a Mac) or choose “Edit > Copy”. Then choose “Edit > Insert Waveform”.
New series of unshielded 45 cm electrode leads with thin cable; suitable for facial EMG and other areas where lighter, shorter lead cables are required. Use for female Touchproof connectors to pinch clip connectors—connect electrodes to either a C-series amplifier or an MEC. The pinch connectors are light weight and the lead cable tinsel wire […]
The new issue of Psychophysiology has a study “Quantifying rapid changes in cardiovascular state with a moving ensemble average” using MEAP for preprocessing/analysis and BIOPAC hardware and software for data collection, display, and storage. The proof of concept study demonstrates a viable method for the adoption of ICG measures across the field of psychophysiology. MEAP (moving ensemble […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering MRI, ECG, and Laser Doppler Flow measurement. fMRI & Thermal Perception: The neural mechanisms underlying thermal perception (how hot or cold we perceive the temperature to be) have not been fully […]
