OProf is a tool that scans a set of DNA sequences aligned with respect to a functional site (e.g. a transcription start site) to determine the frequency of a motif in a region around the functional site. For example it can show the distribution of the TATA-box around promoters.
Inputs can be one of the available data sets, a user provided FASTA file or a users' FPS file.
A motif can be selected from the available libraries, a user provided Position Weight Matrix or a consensus sequence.
Sequence range: is the range around the functional site that OProf scans for the motif
Sliding Window: is the window width and shift used by OProf when scanning for the motif
OProf shows the distribution of the motif around the functional site (in this example the TATA-box in EPDnew promoters, alligned by the TSS).
