Method, device, and computer program for assembling pieces of chromosomes from one or several organisms

摘要

The invention relates to assembling a sequence representing pieces of at least one chromosome from a set of raw sub-sequences representing DNA fragments of a library including DNA fragments comprising chains of contiguous nucleotides and including DNA fragments comprising combinations of at least two chains of contiguous nucleotides. After having obtained first values representing contact frequencies between DNA regions, the first values being associated with second values representing distances between the corresponding DNA regions, the following steps are iteratively carrying out:- updating a genome structure on the basis of the first and second values and on the basis of a theoretical model associating a contact probability between DNA regions with a distance between the corresponding DNA regions, the updated genome structure being representative of the real genome structure of the chromosome; and- updating parameters of the theoretical model as a function of the updated genome structure.
