Sequencing of a diploid PCR product that is heterozygous for an indel mutation and a downstream single nucleotide polymorphism (SNP) allows determination of haplotype phase. Manual determination of phase from trace files of this type is tedious; therefore, we introduce the Perl script TraceHaplotyper, which works from the expected sequence to analyze a sequencing trace file for the sites that are informative for the genotyping and outputs the two underlying haplotypes.
