As everyone likes screenshots, we have produced one for each interface: SHOGUN with Octave, Matlab, Python and R. Click on the link for higher resolution images.
We have successfully used this toolbox to tackle the following sequence analysis problems: Protein Super Family classification, Splice Site Prediction   , Interpreting the SVM Classifier  , Splice Form Prediction , Alternative Splicing  and Promotor Prediction . Some of them come with no less than 10 million training examples, others with 7 billion test examples. A graphical example is written digit recognition as shown below:
We have presented shogun at numerous occassions and provide additional material below
