SADMAMA is designed to address the question of whether one set of sequences has more and/or better binding sites of a particular transcription factor than the other. The binding sites are modeled as matches to a position weight matrix (PWM) which is presumed to be known.
For more details please refer to the paper.
You can download the C source code of the version that was used for the tests mentioned in the paper here. There's a newer version that should be made available soon with some bug fixes and some new features.
