Table 3. Headings and explanation of Data Record 2 format.

Mouse Name	Colony Prefix	Genotype	Zygosity	Sex	Birth Date	Gene Name	Assay Date	Age (weeks)	Pulmonary Metastasis Count	Core Strain	Cell Number Administered (×105)	Dosing Group	Full Strain	Cell Line Used	QC reason
The formatting of Data Record 2 is explained together with a list of all the possible options for some of the key columns.
Unique mouse identifier	Unique identifier for the line—can cross reference the gene list table to look up	Full genotype	Genotype classification—options are wildtype, heterozygote or homozygote (for X linked genes for ease of filtering hemizygote has been set to homozygote)	Sex of the mouse—Female or Male	Date of birth for the mouse	For a mutant mouse the gene that was targeted	Date pulmonary metastasis count was performed	Age of the mouse in weeks on the assay date—only mice with the same assay date can be compared +/− 2 weeks	Count value, blank if data have been QC failed	These are the strain groups of mice that can be combined from a strain perspective	Dose of cells used	These are the cohorts of mice that were administered with the same preparation of cells. Due to subtle differences with each batch of cells only mice within the same dosing group should be compared	The full genetic background of the mouse	Cell line used in the assay	Reason for excluding data as outlined in Table 1
