In this segment of the video, the narrator demonstrates how to analyze data using the free downloadable bsl4 analysis software. The tutorial covers essential analysis techniques such as zooming in and out on data, auto-scaling waveforms, showing and hiding channels, selecting data areas, using measurement boxes, and inserting event marks. The user interface tools for zooming, displaying grids, overlapping waveforms, and adjusting horizontal scaling are explained. The narrator also highlights how to optimize waveforms for better visualization.

In this segment of the video, the focus is on customizing scaling and axis display settings in a waveform visualization tool. The speaker demonstrates how to adjust vertical and horizontal scaling by changing upper and lower bounds, as well as setting the start and end points of the x-axis for a more detailed view. The video also covers taking measurements using the ibeam tool, utilizing grid display, zooming in on data, adjusting waveform spacing, and toggling visibility of channels. Additionally, the speaker shows how to hide specific channels for a cleaner view of the data.

In this part of the video, the speaker explains how to unhide hidden data by holding down the alt or option key and clicking. They discuss measurement boxes above the Channel numbers, showing how to select a Channel and measurement to view specific data. The selected Channel determines which channel the measurements are taken from. The speaker demonstrates selecting beats per minute and using the ibeam tool to measure it. They also cover event markers, showing segment labels and how to navigate through them by clicking or using arrow keys. The video explains how to edit segment descriptions within the event markers.

In this segment of the video, the transcript covers the updated features in the software, including the ability to add user-entered markers for inhale and exhale, displayed as inverted triangles that can be edited. Users can add text annotations to the graph by clicking on the “a” icon and placing it on the waveform, helpful for noting details like start and stop of deep breathing. The text annotation tool can also be used for more detailed zoomed-in markings, such as different parts of an ECG waveform like the p-wave. Annotations remain visible even when zooming out, but they can be cleared by holding down the left mouse button and choosing to clear for the selected Channel or all annotations on the graph. Further guidance on using the software can be found in available resources under the Help menu, additional tutorials online, or by contacting Biopac support.
