Data release 6.0

Release notes: Represents a major data release. Changes include:
  • > 1k additional mouse lines with new data from the IMPC consortium
  • Several changes to the statistical analysis, including:
    • Analysis includes body weight as an effect in the statistical model with the result that several hundred genotype-phenotype associations became non-significant, while the increased sensitivity added several hundred phenotypes that were not previously detected due to weight confounding the analysis
    • Several count parameters (Number of digits, Number of ribs left, Number of ribs right, Number of caudal vertebrae, Number of cervical vertebrae, Number of lumbar vertebrae, Number of pelvic vertebrae, Number of thoracic vertebrae) are now analyzed using the more appropriate Reference Range+ framework resulting in more accurate detection of phenotype
    • All Auditory Brain Stem Response parameters are analyzed using Reference Range+ framework when enough data is available, falling back to a linear mixed model (including jitter when there is no variation) when there is not enough data to establish a reference range
