First Workshop On Pangenomics Algorithms for Omics Data

June 21st, 2019

Univ. Milano-Bicocca. U6 Building – Room Martini (floor -1).

Theme and scope

Computational Pangenomics wants to produce the computational tools for transitioning from a sequence-based genome to graph-based reference genomes, where variants of huge cohorts are represented in a unified way.

Transcriptomics was the first field where the need of imposing a structure over strings has become clear, leading to the notion of a splicing graph to represent all possible transcripts of a gene, as well as the exon-intron structure.

Genome assemblers are increasingly aware that a diploid organism has two different, but very similar, copies of each genome: hence the correct outcome of an assembly cannot be a single string. Finally, metagenomics studies different species that can share portions of the genome: another example where the correct representation of an assembly cannot be linear. Moreover, the 1000 Genomes project has generated new interest in the analysis of a population genome.

The workshop had a previous edition in 2016 focused on Graph assembly algorithm. This time the main aim of the workshop is to bring together researchers that can collaborate on some open problems on graph-based algorithmic approaches to bioinformatics common topics in Bioinformatics.  This year the plan is to apply for the COST program. Since the aim is also stimulate new collaborations, this edition will be mainly focused on the discussion of open problems. To this purpose, part of the day will be focused on the creation of small working groups with each working on an open problem.
