The xwallpaper utility allows you to set image files as your X wallpaper. JPEG, PNG, and XPM file formats are supported, all of them being configurable and therefore no fixed dependencies.

Tool for generating multiple alignments of protein sequences. Using a combination of probabilistic modeling and consistency-based alignment techniques, PROBCONS has achieved the highest accuracies of all alignment methods to date. On the BAliBASE benchmark alignment database, alignments produced by PROBCONS show statistically significant improvement over current programs, containing an average of 7% more correctly aligned columns than those of T-Coffee, 11% more correctly aligned columns than those of CLUSTAL W, and 14% more correctly aligned columns than those of DIALIGN.

trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII form from a file or continuously from a FIFO and displayed in real-time into a multi-pass trend (much like a CRT oscilloscope). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
