Primary data generated from this behavioral phenotyping project are stored in the MouseTrack system (https://mouse.ornl.gov/mousetrack/). The strain means for each trait by sex were deposited into GeneNetwork.org, and the positional candidates and coexpressed gene lists were stored in a database and tool set called ‘ontological discovery environment (ODE)’ (Baker et al. 2009) where they may be integrated with other genomic data sets. The entire analysis path from MouseTrack through GeneNetwork through ODE can be repeated from the primary data in MouseTrack for any individual field. Accession numbers for each trait are listed in Supplementary information, Table S2.
