Phenotype Regression Configuration

A phenotype regression configuration file is used when generating the phenotype browser’s database files for a given study or dataset. It determines which measures to construct regressions against. The format follows the general INI style. Regression configurations can be created as a separate file or embedded in a phenotype database’s own configuration file for ease of access.

Each regression is configured by a section with a name such as [regression.{regression_name}], where regression_name is a user-selected name for the regression. The key-value pairs of a regression section are as follows -

instrument_name

instrument_name = {pheno instrument name}

This is the name of the instrument to which the regressor (or exogenous/independent) measure belongs to. It can be left empty to indicate that the measure is present in all instruments.

measure_name

measure_name = {pheno measure name}

This is the name of the regressor measure.

jitter

jitter = {jitter float value}

A float value that determines the amount of jitter to apply to points when drawing the regression plot. The default value is 0.1.

display_name

display_name = {pheno regression display name}

Determines the name of the regression’s column in the phenotype browser.
