Example 81 with Logger

use of org.apache.logging.log4j.Logger in project gatk-protected by broadinstitute.

the class HDF5PCACoveragePoNCreationUtils method subsetReadCountsToUsableTargets.

/**

     * by the user.

     *     It returns a pair of object, where the left one is the updated read-counts with only the usable
     *     targets, and the right one is the corresponding target factors.
     * </p>
     *
     * @param readCounts the input read-counts.
     * @param targetFactorPercentileThreshold the minimum median count percentile under which targets are not considered useful.
     * @return never {@code null}.
