Angola colobus assembly and gene annotation


The Cang.pa_1.0 assembly was submitted by Baylor College of Medicine on 2015/03/12 . The assembly is on the Scaffold level, consisting of 197,124 assembled into 13,124 scaffolds. The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. The N50 length for the contigs is 38,363 while the scaffold N50 is 7,840,981.

Gene annotation

The Angola colobus, Angolan black-and-white colobus, or Angolan colobus (Colobus angolensis) is an arboreal Old World monkey belonging to the Colobus genus.

The gene annotation process was carried out using a combination of protein-to-genome alignments, annotation mapping from a suitable reference species and RNA-seq alignments (where RNA-seq data with appropriate meta data were publicly available). For each candidate gene region, a selection process was applied to choose the most appropriate set of transcripts based on evolutionary distance, experimental evidence for the source data and quality of the alignments. Small ncRNAs were obtained using a combination of BLAST and Infernal/RNAfold. Pseudogenes were calculated by looking at genes with a large percentage of non-biological introns (introns of <10bp), where the gene was covered in repeats, or where the gene was single exon and evidence of a functional multi-exon paralog was found elsewhere in the genome.

In accordance with the Fort Lauderdale Agreement , please check the publication status of the genome/assembly before publishing any genome-wide analyses using these data.
