  <help>

Convert genotype-based phased alleles within a window size specified by -w option into haplotype alleles. Will break haplotype construction when encountering non-phased genotypes on input.

The options are::

    -w, --window-size N     Merge variants at most this many bp apart (default 30)
    -o, --only-variants     Don't output the entire haplotype, just concatenate
                            REF/ALT strings (delimited by ":")
