Positioning unpositioned contigs. Comparative sequence analysis (CSA) contig positions were compared with the positions predicted by linkage analysis (LA) presented in Liu et al. [19]. The table shows 130 contigs unpositioned in the genome assembly (Btau_4.0) for which contig positions from these two prediction methods are less than 5 Mb apart. Contig, BTA, position given by CSA and position given by LA is presented.

Quality assessment of the bovine genome assembly Btau_4.0. Scaled recombination rate versus physical distance (kb) is plotted for all 29 autosomal bovine chromosomes. Contig positions predicted by comparative sequence analysis are indicated in light grey and contig positions predicted by linkage analysis are indicated in dark grey. Contigs given similar positions by both methods are indicated in light blue.
