There are two ways to browse TreeBASE: with frames and without frames. [Browse with Frames] Browsing with frames is best viewed with a monitor of at least 800 by 600 pixels.The position of the frame dividers are adjustable to accommodate different browser types, so start by tailoring them to your needs (click on a frame divider and drag in one way or the other). Basic Procedure: A. Enter a keyword, select what to search on, and click the "Enter" button (never hit the "Return" key in TreeBASE -- always click on a button). B. Select what you want from the shortlist, and then click "Search." C. To view a tree, click on that tree's name. D. Click on a taxon (or clade) to search on this item. Return to step "B". [Browse Without Frames] This feature produces three separate windows without frames. Resize and rearrange them on your screen to suit your needs. The flow of data is otherwise the same as with frames.
