DNA methylation predictions
Download CpG island feature generator
We developed an application that is designed to generate LIBSVM formatted feature files for existing DNA methylation datasets, that allows users to distinguish between methylated and unmethylated CpG islands. The application can be used to read genomic locations with assigned numeric values. For example, read probe locations and intensities from DNA methylation experiments. Furthermore, the application can map the probes to overlapping CpG islands and lift locations between multiple human genome builds. For each of these locations, a LIBSVM compatible feature string is generated, that may include features, representing up to 15 categories. The user may choose the categories to generate features for. Furthermore, the application can generate support vector regression compatible files (by including the actual methylation values) or support vector classification compatible files (by converting given methylation intensities to binary states).
Afterwards, any machine learning approach can be applied to the generated features to create a model on those. The generated model can then be applied to novel data to predict, e.g., unknown methylation states of CpG islands.
