TChard is a datset for TCR-peptide/-pMHC binding prediction. It includes more than 500,000 samples, derived from heterogenous sources, such as IEDB, VDJdb, McPAS-TCR and the NetTCR-2.0 repository. Since the samples included in the TChard dataset derive from different datasets, we include a `license` column in the CSV file. The `license` column specifies from which original dataset a sample comes, and which license applies. Experiments on this dataset can be found in the GitHub repository: https://github.com/nec-research/tc-hard
