BSL PRO 4 Manual - Biopac

228 BSL PRO ManualOverviewChapter 12Edit Menu commandsOne of the most useful features in BSL PRO is the ability to edit and work with data by cutting sections andcopying sections from one window to another. In this sense, the MP System (MP36, MP35 or MP45) allowsyou to work with data much as a word processor lets you work with text. When working with data, you willusually want to select a section of data to work with. To select a section of data, use the editing tool tohighlight an area. The selection tool is used for a variety of purposes including cutting and pasting waveformdata, making measurements and determining which portion of a waveform to save as text values. To select thetool, click its icon in the lower right hand corner. You will notice that the cursor changes into the familiar “Ibeam”cursor when you move it within the graph area. Click the mouse and drag to select a portion of thewaveform.IMPORTANTWhen multiple waveforms are present, the highlighted area appears to include all of thewaveforms, but most modifications and transformations apply only to the selected channel.Once you have selected a section of a waveform, you can perform such as editing, transformations, savingdata to the journal, saving as text, and using the measurement functions on the selected area. The cursoralways selects at least one sample point; when there is no defined area, a single sample point will be selected,and the cursor will blink. You can highlight a larger area by positioning the cursor over the first point you areinterested in, holding down the mouse button, and dragging the cursor either left or right to highlight an area.This is similar to highlighting a series of letters or words in a word processor. You can modify the selectedarea by placing the cursor anywhere on the graph, then holding down the shift key and clicking the mouse.This feature is useful for fine-tuning the selected area. To fine tune, first coarsely select an area. By zoomingin (with the zoom tool) on either edge, you can then use the shift key to precisely align the edges of theselected area.BSL PRO also allows you to select an area that spans multiple screens. To do this, first select an area thatcontains the leading edge of the portion of the graph that you are interested in. Next, use the horizontal scrollbar to scroll to the end of the area that you are interested in. Then place the mouse near the area of interest andclick the button while holding down the shift key. While still depressing the mouse button, move the cursor tothe exact position desired.By using the selection tool to select areas of the waveform, the Cut, Copy, Paste and Clear functions aredesigned to work in much the same manner as a word processor. These functions operate only on areasselected by the selection tool.Visit the online support center at www.biopac.com
