This mode is used to perform feature selection with min/max statistics. For each feature, the minimum and maximum feature values in the positive and in the negative class is determined. These values are referred to as minL0, minL1, maxL0 and maxL1. We evaluate the quantity (maxL1 − maxL0) / (minL1 − minL0) and rank features by this quantity. It is implemented by org.bdval.DiscoverWithMinMax.

Mode Parameters

The following options are available in this mode

Flag Arguments Required Description
--pathway-components-dir pathway-components-dir no Directory where pathway components will be stored. (default: pathway-components)
--ratio ratio no The Min/Max value used as threshold. (default: 0.5)
--min-max-observations min-max-observations no The number of min/max elements to observe to compute Min/Max statistics. (default: 1)
--output-gene-list n/a no Write features to the output in the tissueinfo gene list format.
--report-max-probes report-max-probes no Restrict output to the top ranked probes. This option works in conjunction with ratio and can further restrict the output.
