4.3 The current version (online since July 2023). New in this version:
  • NetMHCIIpan-4.3 is trained on an extended dataset of MHC eluted ligands, incorporating new data for HLA-DP, HLA-DR and BoLA-II. Furthermore, an update to the NNAlign_MA machine learning framework allows for prediction of inverted peptide binders.
Main publication:
  • Accurate prediction of HLA class II antigen presentation across all loci using tailored data acquisition and refined machine learning

    Science Advances, 24 Nov 2023. https://www.science.org/doi/10.1126/sciadv.adj6367
4.2 (online since September 2022). New in this version:
  • NetMHCIIpan-4.2 is trained on an extensive dataset of both eluted ligand (EL) and binding affinity (BA) data, including new novel EL data for 14 HLA-DQ molecules. Further, a 'distance to training data' metric is printed for each selected molecule in the same way as NetMHCpan-4.1, indicating how reliable the predictions are.
Main publication:
  • Machine learning reveals limited contribution of trans-only encoded variants to the HLA-DQ immunopeptidome

4.1 (online since Sept 2021). New in this version:
  • The method is trained on a extented set of EL data compared to version 4.0, and novel and correct BA for HLA-DQA1*04:01-DQB1*04:02 are included. Further is DRB3, 4 and 5 allele information predicted from DRB1 based on linkage disequilibrium with DRB1 when absent from typing data.
Main publication:

  • Accurate MHC Motif Deconvolution of immunopeptidomics data reveals high relevant contribution of DRB3, 4 and 5 to the total DR Immunopeptidome

4.0 (online since April 2020). New in this version:
  • The two output neuron architechture introduced in NetMHCpan-4.0 permits the inclusion of EL data, and the new training algorithm NNAlign_MA extends training data to ligands of ambiguous allele assignments. The model also, optionally, encodes ligand context.
