**What it does**

CONTRA is a tool for copy number variation (CNV) detection for targeted resequencing data such as those from whole-exome capture data. CONTRA calls copy number gains and losses for each target region with key strategies include the use of base-level log-ratios to remove GC-content bias, correction for an imbalanced library size effect on log-ratios, and the estimation of log-ratio variations via binning and interpolation. It takes standard alignment formats (BAM/SAM) and output in variant call format (VCF 4.0) for easy integration with other next generation sequencing analysis package.

**Required Parameters**

::

  -t, --target         Target region definition file [BED format] 

  -s, --test           Alignment file for the test sample [BAM/SAM] 

  -c, --control        Alignment file for the control sample 
                       [BAM/SAM/BED – baseline file]

  --bed                **option has to be supplied for control
                       with baseline file.** 

  -f, --fasta          Reference genome [FASTA]

  -o, --outFolder      the folder name (and its path) to store the output 
                       of the analysis (this new folder will be created – 
                       error message occur if the folder exists) 

-----

**Optional Parameters**

::

  --numBin              Numbers of bins to group the regions. User can 
                        specify multiple experiments with different numbers
                        of bins (comma separated). [Default: 20] 

  --minReadDepth        The threshold for minimum read depth for each bases 
                        (see Step 2 in CONTRA workflow) [Default: 10] 

  --minNBases           The threshold for minimum number of bases for each 
                        target regions (see Step 2 in CONTRA workflow) 
                        [Default: 10] 

  --sam                 If the specified test and control samples are in 
                        SAM format. [Default: False] (It will always take 
                        BAM samples as default) 

  --bed                 If specified, control will be a baseline file in 
                        BED format. [Default: False] 
                        Please refer to the Baseline Script section for 
                        instruction how to create baseline files from set 
                        of BAMfiles. A set of baseline files from different 
                        platform have also been provided in the CONTRA 
                        download page. 

  --pval                The p-value threshold for filtering. Based on Adjusted 
                        P-Values. Only regions that pass this threshold will 
                        be included in the VCF file. [Default: 0.05] 

  --sampleName          The name to be appended to the front of the default output 
                        name. By default, there will be nothing appended. 

  --nomultimapped       The option to remove multi-mapped reads 
                        (using SAMtools with mapping quality > 0). 
                        [default: FALSE] 

  -p, --plot            If specified, plots of log-ratio distribution for each 
                        bin will be included in the output folder [default: FALSE] 

  --minExon             Minimum number of exons in one bin (if less than this number
                        , bin that contains small number of exons will be merged to 
                        the adjacent bins) [Default : 2000] 

  --minControlRdForCall Minimum Control ReadDepth for call [Default: 5] 

  --minTestRdForCall    Minimum Test ReadDepth for call [Default: 0] 

  --minAvgForCall       Minimum average coverage for call [Default: 20] 

  --maxRegionSize       Maximum region size in target region (for breaking 
                        large regions into smaller regions. By default, 
                        maxRegionSize=0 means no breakdown). [Default : 0] 

  --targetRegionSize    Target region size for breakdown (if maxRegionSize 
                        is non-zero) [Default: 200] 

  -l, --largeDeletion   If specified, CONTRA will run large deletion analysis (CBS).
                        User must have DNAcopy R-library installed to run the 
                        analysis. [False] 

  --smallSegment        CBS segment size for calling large variations [Default : 1] 

  --largeSegment        CBS segment size for calling large variations [Default : 25] 

  --lrCallStart         Log ratios start range that will be used to call CNV 
                        [Default : -0.3] 

  --lrCallEnd           Log ratios end range that will be used to call CNV 
                        [Default : 0.3] 

  --passSize            Size of exons that passed the p-value threshold compare 
                        to the original exons size [Default: 0.5]
