**What it does**

This tool identifies simple as well interrupted STRs. Choosing a hamming distance of zero will return simple STRs. 
Choosing a hamming distance of greater than zero will return both simple and interrupted STRs. 
The algorithms used to identify simple and interrupted STRs are described oin the manuscript cited below (see TABLE XXXX).

**Citation**

When you use this tool, please cite **Fungtammasan A, Ananda G, Hile SE, Su MS, Sun C, Harris R, Medvedev P, Eckert K, Makova KD. 2015. Accurate Typing of Short Tandem Repeats from Genome-wide Sequencing Data and its Applications, Genome Research**
This tool is developed by Chen Sun (cxs1031@cse.psu.edu) and Bob Harris (rsharris@bx.psu.edu)
 
**Input**

- The input files can be fastq, fasta, fastq without quality score, and SAM format.

**Output**

For fastq, the output will contain the following columns:

- Column 1 = length of STR (bp)
- Column 2 = length of left flanking region (bp)
- Column 3 = length of right flanking region (bp)
- Column 4 = repeat motif (bp)
- Column 5 = hamming distance 
- Column 6 = read name
- Column 7 = read sequence with soft masking of STR
- Column 8 = read quality (the same Phred score scale as input)

For fasta, fastq without quality score and sam format, column 8 will be replaced with dot(.).

If the users have mapped file (SAM) and would like to profile STRs from premapped data instead of using flank-based mapping approach, they can select SAM format input and specify that they want correspond STRs in reference for comparison. The output will be as follow:

- Column 1 = length of STR (bp)
- Column 2 = length of left flanking region (bp)
- Column 3 = length of right flanking region (bp)
- Column 4 = repeat motif (bp)
- Column 5 = hamming distance 
- Column 6 = read name
- Column 7 = read sequence with soft masking of STR
- Column 8 = read quality (the same Phred score scale as input)
- Column 9 = read name (The same as column 6)
- Column 10 = chromosome 
- Column 11 = left flanking region start
- Column 12 = left flanking region stop
- Column 13 = STR start as infer from pair-end
- Column 14 = STR stop as infer from pair-end
- Column 15 = right flanking region start
- Column 16 = right flanking region stop
- Column 17 = STR length in reference
- Column 18 = STR sequence in reference
