#31 Bioinformatics Contest 2019 with Alexey Sergushichev and Gennady Korotkevich

March 24, 2019

The third Bioinformatics Contest took place in February 2019.

Alexey Sergushichev, one of the organizers of the contest, and Gennady Korotkevich, the 1st prize winner, join me to discuss this year’s problems.

#30 Bayesian inference of chromatin structure from Hi-C data with Simeon Carstens

February 27, 2019

Hi-C is a sequencing-based assay that provides information about the 3-dimensional organization of the genome. In this episode Simeon Carstens explains how he applied the Inferential Structure Determination (ISD) framework to build a 3D model of chromatin and fit that model to Hi-C data using Hamiltonian Monte Carlo and Gibbs sampling.

#29 Haplotype-aware genotyping from long reads with Trevor Pesout

January 27, 2019

Long read sequencing technologies, such as Oxford Nanopore and PacBio, produce reads from thousands to a million base pairs in length, at the cost of the increased error rate. Trevor Pesout describes how he and his colleagues leverage long reads for simultaneous variant calling/genotyping and phasing. This is possible thanks to a clever use of a hidden Markov model, and two different algorithms based on this model are now implemented in the MarginPhase and WhatsHap tools.
