VCFchain and query performance. a The total network storage used by a VCFchain (storing 6,458,146 variants) as a function of the number of nodes in the network. b The storage, time, and memory requirements of building and inserting data to a VCFchain in a single-node network as a function of the number of reads stored in the chain. Storage is compared to that used by a VCF file. c The time requirements for VCFquery as a function of the number of reads stored in the chain, compared to the retrieval time from a VCF file using BCFtools. d The output of VCFquery compared to that of BCFtools for a given read
