BSL PRO 4 Manual - Biopac

42 BSL PRO ManualTransform dataBSL PRO includes a library of functions to transform data or perform mathematicalcalculations on waveform data. All of these options can be found under the Transform andAnalysis menus, and are discussed in detail in the Analysis section beginning on page262.When performing transformations If a section of a waveform is highlighted, the transformation will apply to thatsection. If no area is selected, BSL PRO will always select a single data point. If the transformation can only be performed on a selected area (digitalfiltering, for instance) and a single point is selected, the entire waveform willbe used (and the transform entire wave option will be disabled; close out ofthe dialog and select an area if desired).Focus AreasFocus areas are comprised of selected time ranges within the graph. The purpose of the “Focus on” tool is toeasily isolate selected areas within the graph window for discrete analysis. This can be useful for identifying areasof interest within a larger data set by highlighting, naming and storing them permanently in the graph. When afocus area is assigned, that portion of the graph will appear shaded with borders appearing at the edges. Theassigned focus area label will be displayed vertically in the shaded area. (See following page for example.) Focusareas may also be defined via the “Focus on” toolbar above the graph, and in the Find Cycle Analysis feature. Focus areas are graph level data, similar to events. Defining a focus area in one data view defines it for alldata views, etc. Focus areas are drawn only for graph windows in chart, stacked plot, or scope mode. They are overlaid ontop of data and events but underneath text annotations and selections. Focus areas may overlap. Each focus area is required to have a unique name.Creating Focus AreasTo create a focus area:1. Select an area of interest in the graph data using the I-beam tool or selection palette.2. Create the focus area using one of the following methods:Click on the “Add” (+) button to the right of the “Focus on” toolbar.Choose “Display > Create Focus Area”.Right-clicking in the graph and choosing “Create Focus Area” from the contextual menu.3. Name the focus area by typing into the label field.The new focus area label will appear in the “Focus on” toolbar field.The new focus area and label will appear in the graph.Visit the online support center at www.biopac.com
