Chromosome-length genome assembly
Download the CU_Lasu_v1_HiC.fasta.gz file containing the chromosome-length assembly of the superb starling genome. All modifications with respect to the draft (see below) are annotated in the CU_Lasu_v1_HiC.assembly file. Some basic stats associated with the new reference, CU_Lasu_v1_HiC, are listed below. The full data release can be explored here.

Draft
The chromosome-length genome assembly is based on the draft assembly CU_Lasu_v1 (GCA_015883425.1), credited below.

Feather Gene Expression Elucidates the Developmental Basis of Plumage Iridescence in African Starlings. J. Hered. 112, 417-429. https://doi.org/10.1093/jhered/esab014.
Method
3D Assembly was performed using 3D-DNA pipeline (Dudchenko et al., Science, 2017). The genome was reviewed using Juicebox Assembly Tools (Dudchenko et al., bioRxiv, 2018). See Methods for more information.
Hi-C sample
The blood sample for in situ Hi-C preparation was donated by a female individual, and provided to us by SeaWorld.
Hi-C Contact maps
Hi-C data was aligned to the draft reference using Juicer (Durand, Shamim et al., Cell Systems, 2016), and contact maps visualizing the alignments with respect to the draft and the new reference were built using 3D-DNA (Dudchenko et al., Science, 2017). The contact maps can be explored below via Juicebox.js interactive tool (Robinson et al., Cell Systems, 2018). To explore the assembly in greater detail, please download the .hic and .assembly files from the data release folder and use Juicebox Assembly Tools (Dudchenko et al., bioRxiv, 2018).
