Currently two databases are available: + +-- **ChIP peaks** from 191 ChIP experiments (processed from hmChIP database, see individual peak/BED files in **Shared Data**) + +-- **Annotated gene features**, such as: TSS, TES, 5'ss, 3'ss, CDS start and end, miRNA seed matches, enhancers, CpG island, microsatellite, small RNA, poly A sites (3P-seq-tags), miRNA genes, and tRNA genes. + +Two output files are generated. One is the coverage/profile for each feature in the database that has a minimum overlap with the query set. The first two columns are feature name and the total number of overlapping intervals from the query. Column 3 to column 102 are coverage at each bin. The other file is an PDF file plotting both the heatmap for all features and the average coverage for each individual database feature. + + +**How it works** + +For each interval/peak in the query file, a window (default 10,000bp) is created around the center of the interval and is divided into 100 bins. For each database feature set (such as Pol II peaks), the tool counts how many intervals in the database feature file overlap with each bin. The count is then averaged over all query intervals that have at least one hit in at least one bin. Overall the plotted 'average coverage' represnts the fraction of query features (only those with hits, number shown in individual plot title) that has database feature interval covering that bin. The extreme is when the database feature is the same as the query, then every query interval is covered at the center, the average coverage of the center bin will be 1. + +The heatmap is scaled for each row before clustering. + + </help> +</tool> +

The default setting is to move the interval to any chromosome, with the probability proportional to the size/length of the chromosome. You can have it pick a random position in the same chromosome, such that in the randomized set each chromosome has the same number of intervals as the reference set. The size of the chromosome can be either learned from the reference set (chromosome size = max(interval end)) or read from a chromosome size file.
