**DimontPredictor** allows for predicting binding sites in new data using a previously trained Dimont model. For training a Dimont model see tool "Dimont".

This tool may be useful if you, for instance, want to predict binding sites of a previously discovered motifs in other data sets, or if you want to try different p-values for filtering predictions.

Input sequences must be supplied in an annotated FastA format as a file uploaded by the "Upload File" task in section "Get Data" of Galaxy or generated using the "Dimont Data Extractor" tool.
In the annotation of each sequence, you need to provide a value that reflects the confidence that this sequence is bound by the factor of interest.
Such confidences may be peak statistics (e.g., number of fragments under a peak) for ChIP data or signal intensities for PBM data.

For instance, an annotated FastA file for ChIP-exo data could look like::
	
	> signal: 515
	ggccatgtgtatttttttaaatttccac...
	> signal: 199
	GGTCCCCTGGGAGGATGGGGACGTGCTG...
	...

where the confidence for the first two sequences amounts to 515 and 199, respectively.
The FastA comment may contain additional annotations of the format ``key1 : value1; key2: value2;...``.
We also provide an example_ input file.

Accordingly, you would need to set the parameter "Value tag" to ``signal`` for this input file.

The parameter "Weighting factor" defines the proportion of sequences that you expect to be bound by the targeted factor with high confidence. For ChIP data, the default value of ``0.2`` typically works well. 
For PBM data, containing a large number of unspecific probes, this parameter should be set to a lower value, e.g. ``0.01``.

The parameter "p-value" defines a threshold on the p-values of predicted binding sites, and only binding sites with a lower p-value are reported by DimontPredictor.
The Dimont tool uses a p-value threshold of ``1E-3``, which is also the default value of DimontPredictor.

You can also install this web-application within your local Galaxy server. Instructions can be found at the Dimont_ page of Jstacs. 
There you can also download a command line version of DimontPredictor.
