Schema of data flow in TTS mapping. A chromosome coordinate is used to initiate a search of pTTSs in a given region and map pTTSs to several annotation tracks. The pTTSs search parameters should be provided by user or by default. The results of the search are reported in a summary table and also forward to map the given pTTS to selected annotation tracks. After mapping all pTTSs to available annotation tracks, the number of found annotation tracks, the number of the annotation tracks overlapped with these pTTSs, and number of the pTTSs overlapped with the annotation tracks are reported to summary table.
