Abstract
AbstractCurrent mitochondrial DNA (mtDNA) haplogroup classification tools map reads to a single reference genome and perform inference based on the detected mutations to this reference. This approach biases haplogroup assignments towards the reference and prohibits accurate calculations of the uncertainty in assignment. We presentHaploCart, an mtDNA haplogroup classifier which usesVG’s pangenomic reference graph framework together with principles of Bayesian inference. We demonstrate that our approach significantly outperforms available tools by being more robust to lower coverage or incomplete consensus sequences and producing phylogenetically-aware confidence scores that are unbiased towards any haplogroup.HaploCartis available both as a command-line tool and through a user-friendly web interface. The program written inC++accepts as input consensus FASTA, FASTQ, or GAM files, and outputs a text file with the haplogroup assignments along with confidence estimates. Our work considerably reduces the amount of data required to obtain a confident mitochondrial haplogroup assignment.HaploCartis available as a command-line tool athttps://github.com/grenaud/vganand as a web server athttps://services.healthtech.dtu.dk/service. php?HaploCart.
