Workflow chart of the ab initio motif detection procedure. A) The chart describes the algorithmic steps for the ab initio motif detection process. The thick arrows correspond to algorithmic flows after decision points, the dashed arrows represent initialization steps which are performed uniquely and the dotted arrows (Motif Searching part) concern independently implemented alternative data processing scenarios. The details of the procedure are described in Materials and Methods. B) Description of the workflow symbols.
