SampleDb - Example human immune repertoire data


A data.frame of example V(D)J immunoglobulin sequences derived from a single individual (PGP1), sequenced on the Roche 454 platform, and assigned by IMGT/HighV-QUEST to IGHV1 family alleles.


A data.frame where rows correspond to unique V(D)J sequences and columns include:

  • "SEQUENCE_IMGT": IMGT-gapped V(D)J nucleotide sequence.
  • "V_CALL": IMGT/HighV-QUEST V segment allele calls.
  • "D_CALL": IMGT/HighV-QUEST D segment allele calls.
  • "J_CALL": IMGT/HighV-QUEST J segment allele calls.
  • "JUNCTION_LENGTH": Junction region length.
