Mexican volcano mouse (Neotomodon alstoni)
Both the male and female Mexican volcano mice play an equally involved role in rearing offspring, such as building and protecting nests and grooming the young. Read more about Mexican volcano mice on Animal Diversity's website.

Chromosome-length genome assembly
Download the Neotomodon_alstoni_10x_v13_HiC.fasta.gz file containing the chromosome-length (2n=48) assembly of the Mexican volcano mouse genome. All modifications with respect to the draft (see below) are annotated in the Neotomodon_alstoni_10x_v13_HiC.assembly file. Some basic stats associated with the new reference, Neotomodon_alstoni_10x_v13_HiC, are listed below. The full data release can be explored here.

Draft
The chromosome-length genome assembly is based on the draft assembly Neotomodon_alstoni_10x_v13, credited below.
The chromosome-length genome assembly was created in collaboration with the MacManes lab, University of New Hampshire. The draft genome assembly was generated using 10X data and scaffolded using Oxford Nanopore data by Matthew MacManes, Anna Tigano and Jocelyn Colella, University of New Hampshire.
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 tissue sample for in situ Hi-C preparation was donated by a female individual, and obtained from The MacManes Lab, University of New Hampshire.
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). (Please note that the interactive figures are scaled 1:2.) 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).
