Fig. 1From: SNooPer: a machine learning-based method for somatic variant identification from low-pass next-generation sequencingWorkflow of SNooPer’s algorithm. SNooPer uses both normal and tumor files in a SAMtools mpileup format as input. It requires a training phase in which an orthogonal validation (re-sequencing) dataset is used to train the RF classification model that is subsequently used to call somatic variations in the test dataset. Light grey boxes represent the training steps while dark grey boxes represent calling steps. Dotted boxes represent optional steps in the workflow. Circles represent the output following either the training or calling phasesBack to article page
