Fig. 1From: Immune repertoire fingerprinting by principal component analysis reveals shared features in subject groups with common exposuresWorkflow 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 repertoiresBack to article page
