Workflow of repertoire fingerprinting by principal component analysis. To perform repertoire fingerprinting we first sequenced antibody genes of human donors and tabulated the IGHV-IGHJ gene pair usages. We then processed the data by subsampling to uniform depth over 10 replicates per donor and normalized counts by Z score transformation. We used PCA to project the input features onto 2 dimensions and analyze gene pairs that contribute to differences between repertoires
