download the main package, supplementary files (some more functions for plotting, doing multi-class classification, other utils; highly undocumented!), and a short FAQ. the SVM part of the code was adapted from LS-SVMlab, though ultimately SVM training is done with simple matlab matrix division. in order to duplicate results from the paper, you will also need RNAs from RFAM and folding software from ViennaRNA. matlash
a nascent project to convert matlab figures into flash objects.
for example, you can type in matlab,
>> x = linspace(0,2*pi,50);
and get a flash object to embed in a web page:
>> plot(x,cos(x),'r'); hold on; plot(x,sin(2*x),'b'); >> matlash here's how it works:
