+**What it does**
+
+SPAN Semi-supervised Peak Analyzer is a tool for analyzing ChIP-seq data.
+
+-----
+
+**Inputs**
+
+*-t, --treatment <Path>*        **Required.** ChIP-seq treatment file. bam, bed or .bed.gz file; If multiple files are given, treated as replicates.
+
+*--chrom.sizes, --cs <Path>*    **Required.** Chromosome sizes path, can be downloaded at http://hgdownload.cse.ucsc.edu/goldenPath/<build>/bigZips/<build>.chrom.sizes
+
+*-c, --control <Path>*          Control file. bam, bed or bed.gz file; Single control file or separate file per each treatment file required.
+
+*--fragment <Integer>*          Fragment size, read length if not given
+
+*-b, --bin <Integer>*           Bin size
+
+*-f, --fdr <Double>*            Fdr value
+
+*-g, --gap <Integer>*           Gap size to merge peaks
+
+*-p, --peaks <Path>*            Path to result peaks file in ENCODE broadPeak (BED 6+3) format
+
+
+-----
+
+**Outputs**
+
+This tool produces a SPAN binary model file and/or peaks in ENCODE broadPeak (BED 6+3) format.
+
+Peak file columns contain the following data:
+
+* **1st**: chromosome name
+* **2nd**: start position of peak
+* **3rd**: end position of peak
+* **4th**: name of peak
+* **5th**: integer score for display in genome browser (e.g. UCSC)
+* **6th**: strand, either "." (=no strand) or "+" or "-"
+* **7th**: fold-change
+* **8th**: -log10pvalue
+* **9th**: -log10qvalue
+
+-----
+
+**SPAN workflow**
+
+* Convert raw reads to tags using *FRAGMENT* parameter.
+* Compute coverage for all genome tiled into bins of *BIN* base pairs.
+* Fit 3-state hidden Markov model that classifies bins as ZERO states with no coverage, LOW states of non-specific binding, and HIGH states of the specific binding.
+* Compute posterior HIGH state probability of each bin.
+* Trained model is saved into *.span* binary format.
+* Peaks are computed using trained model and *FDR* and *GAP* parameters.
+
