How to get the last page of a paged display to start at the correct boundary

Q: When using the Raven paged displays, a user wanted to print each page of the spectrogram. Her pages were set to 10 seconds long, and her page increment was 100%, allowing her to page though the sound with no overlap. However, the sound was 67 seconds long so the pages started at 0, 10, 20, 30, 40, 50, and 57 seconds. She wanted the last page to start at 60 seconds, not 57.

A: Raven reads a full page at a time. If there is only a partial page at the end of the sound, Raven will reuse some of the previous page to create a full page. When you use the scroll bar for the paged display, you are paging to the end of the sound, then subtracting the page size from the end to see where the page should start.

A way to get around this problem is to go to the last page of the file, then use the “Configure View Axes” menu item on the View menu (or in the context-sensitve menus within the views). In the above example, the user should type 60 for the time position in the dialog. This will move the start of the view to the 60-second position, allowing her to print the final 7 seconds of her sound.
