**What it does**

SEACR (Sparse Enrichment Analysis for CUT&RUN) is intended to call peaks and enriched regions from sparse CUT&RUN or chromatin profiling data in which background is dominated by "zeroes" (i.e. regions with no read coverage).

CUT&RUN is an efficient epigenome profiling method that identifies sites of DNA binding protein enrichment genome-wide with high signal to noise and low sequencing requirements. Currently, the analysis of CUT&RUN data is complicated by its exceptionally low background, which renders programs designed for analysis of ChIP-seq data vulnerable to oversensitivity in identifying sites of protein binding.

SEACR is a highly selective peak caller that definitively validates the accuracy of CUT&RUN for datasets with known true negatives. SEACR uses the global distribution of background signal to calibrate a simple threshold for peak calling. SEACR discriminates between true and false-positive peaks with near-perfect specificity from gold standard CUT&RUN datasets and efficiently identifies enriched regions for several different protein targets.

**Input**

SEACR requires files in UCSC bedgraph format from paired-end sequencing as input, which can be generated from read pair BED files.

**Output**

Results are stored in BED files with the folowing format.

::

    <chr>   <start> <end>   <total signal>  <max signal>    <max signal region>

with

- <chr> Chromosome
- <start> Start coordinate
- <end> End coordinate
- <total signal> Total signal contained within denoted coordinates
- <max signal> Maximum bedgraph signal attained at any base pair within denoted coordinates
- <max signal region> Region representing the farthest upstream and farthest downstream bases within the denoted coordinates that are represented by the maximum bedgraph signal
