These are the files of the assemblies that were generated for the manuscript: T. B. Wooldridge, M. Escalona, B. W. Perry, A. N. Enstrom, D. Salih, W. E. Seligmann, S. Sacco, K. L. Moon, R. Sahasrabudhe, N. Chumchim, O. Nguyen, J. L. Kelley, R. D. E. MacPhee, B. Shapiro, Chromosome-scale genomes show rapid diversification and ancient gene flow among bear species. Genome Biol. Evol., evaf188 (2025). DOI: 10.1093/gbe/evaf188 This is a complementary resource for the manuscript. Additional code corresponding to the analyses in the manuscript can be found here: https://github.com/twooldridge/BearComparativeGenomics These have also been submitted to NCBI and should be available soon. We are sharing all the information that has been made available to us from NCBI, while the genomes are still being processed, and the NCBI platform is, as of the day of this submission, under the following notice: Notice: Because of a lapse in government funding, the information on this website may not be up to date, transactions submitted via the website may not be processed, and the agency may not be able to respond to inquiries until appropriations are enacted. The NIH Clinical Center (the research hospital of NIH) is open. For more details about its operating status, please visit cc.nih.gov. Updates regarding government operating status and resumption of normal operations can be found at opm.gov. The files here are the ones submitted to NCBI. The sequences are named: SCAF_X, where X is a number, and they are ordered based on sequence length. For the assemblies tagged as chromosome-level assemblies, we are sharing a table that specifies the relationship between the names. Please follow the prefix of the assemblies to get the CSV file corresponding to the chromosome-assignment table.
