This mode is used to perform univariate feature selection with Kendall tau rank correlation coefficient. The value of the feature is correlated with the label (converted to 0/1). If the absolute value of Kendall tau is more than a threshold (indicating positive or negative correlation), then the feature is selected as an informative biomarker.

It is implemented by

Mode Parameters

The following options are available in this mode

Flag Arguments Required Description
--ratiorationoThe Kendall tau value used as threshold. Default Tau > = 0.5.
--output-gene-listn/anoWrite features to the output in the tissueinfo gene list format.
--report-max-probesreport-max-probesnoRestrict output to the top ranked probes. This option works in conjunction with the ratio and can further restrict the output.
