Waggawagga is a web-based tool for the comparative visualization of coiled-coil predictions and the detection of stable single xcexb1-helices (SAH domains). Overview schemes show the predicted coiled-coil regions found in the query sequence and provide sliders, which can be used to select segments for detailed helical wheel and helical net views. A window-based score has been developed to predict SAH domains. Export to several bitmap and vector graphics formats is supported.
