        BASIL is a method to detect breakpoints for structural variants (including insertion breakpoints) from aligned paired HTS reads in BAM format.  Use BASIL to analyze BAM files for tentative insertion sites.

        Note that BASIL will in general detect all kinds of breakpoints, e.g. for inversions on real-world data.

        BASIL VCF fields

        A typical line in BASIL might look as follows.

        1 5001 site_0 T <INS>   . PASS IMPRECISE;SVTYPE=INS GSCORE:CLEFT:CRIGHT:OEALEFT:OEARIGHT    46.4256:10:12:35:32

        The first seven columns are as usually in VCF files (ref name, 1-based position, reference base, abbreviation for long insertion, no assigned quality, passing all filters, imprecise insertion SV).

        The eighth column contains the names of the score values given in the ninth column:

        GSCORE Geometric mean of the sum of "1 + $score" for all of the following scores.
        CLEFT Number of clipping signatures supporting the site from the left side.
        CRIGHT Number of clipping signatures supporting the site from the right side.
        OEALEFT Number of OEA alignments supporting the site from the left.
        OEARIGHT Number of OEA alignmetns supproting the site from the right.

        Generally, one should filter for a minimum support of OEA records on each side, e.g. a value of 10 makes sense for a 30x coverage and showed good results on simulated data.

        For a ranking, GSCORE is a suitable measure but we did not develop any statistical model for BASIL matches and it is a mean of pseudocounts only. It carries no statistically precise meaning.
