Filtering methods. The circles indicate terms, the gray arrows indicate “is a” relationships, and the blue arrows indicate metaQuantome filtering procedures. (A) Filtering results by number of unique peptides. The numbers inside each term indicate the hypothetical number of peptides giving evidence to each term. (B) Filtering by the number of sample children. The number inside each term indicates the number of children (direct descendants) that term has within the sample. metaQuantome filters out terms that are neither leaves nor meet the user-specified criterion for minimum sample children (here, two, which is the default). (C) Filtering by the number of samples in which the term was quantified.
