Raw experimental data

The ‘experiment’ data core contains raw measurements collected on individual specimens. As described in the documentation on mouse phenotyping, IMPC experiments are organized in pipelines, procedures, and parameters. They are carried out on specimens with a traceable genotype and sex. 

Some notable data fields available in the ‘experiment’ core are in the table below.

Field nameDescription
gene_symbolMouse gene identifier in symbol format, e.g. Car4
gene_accession_idMouse gene identifier in MGI id format, e.g. MGI:1096574
pipeline_stable_idIdentifier of IMPRESS pipeline
procedure_stable_idIdentifier of phenotyping procedure
allele_accession_idAllele stable identifier
zygosityZygosity of the mutant specimens
sexSex of the mutant specimens
weightWeight of specimen
parameter_stable_idIdentifier for phenotyping procedure
data_pointMeasured value

Note. – Phenotyping related identifiers can be found in IMPRESS.

Several other fields are also available; a complete list of available parameters is available here
