fastprofkernel is a Debian package that uses an accelerated version of the original profile kernel  to automatically train SVM based classification models. It can assign user-defined classes to so far uncharacterized proteins.
The package ships with two executable: profkernel-core and profkernel-workflow.
profkernel-core is a speed-optimized, but input/output identical variant of the original profile kernel implementation.
profkernel-workflow uses profkernel-core and trains or applies a SVM based classification model. It provides two modes of operation. In the first mode, 'training', the user provides evolutionary protein profiles and their class assignments (labels) as input and profkernel-workflow outputs a folder with all model files required for predictions. In the second mode, 'prediction', the user provides the path to such a model folder and to the query profiles. profkernel-workflow then predicts their classes.
We have included both executables in a Debian package, together with man pages and a sample classification problem. There are two common ways to install it.
- Via our Debian repository (package "fastprofkernel").
- By manual download and installation of the binary .deb package (please see the manual of your distribution for how to install .deb packages).
For installation on non-Debian based systems, you can download the .tar.gz source package and compile and install it with the included make based installation (see the README file).
