The database of TCR-peptide-MHC modeled structures from the paper: "Large-scale template-based structural modeling of T-cell receptors with known antigen specificity reveals complementarity features"

Models_VDJdb.tar.gz: contains TCR-peptide-MHCI modeld structures and 29 templates, discussed in the paper "Large-scale template-based structural modeling of T-cell receptors with known antigen specificity reveals complementarity features"  

VDJdb_Models_annotation_w_new_names.csv: spreadsheet containing annotations of the modeled structures. The following column names are used:

• vdjdb.pdb.id: model name in the attached database
• cdr3.alpha: CDR3α amino acid sequence
• cdr3.beta: CDR3β amino acid sequence
• orig.alpha(/beta): if “TRUE”, the CDR3α/β sequence is the same as in the corresponding original PDB template. If “FALSE”, the CDR3α/β carries one amino acid substitution (illustrated in the mutation.signature column).
• vdjdb.pdb.id.from: PDB structure that was used as a template for the modeling
• mutation.signature: illustration of the introduced substitution
• pdb.id:  the model name, used during the analysis of the discussed results in the paper.  

Annotation_file_NEW_MUTATOR_RUN_w_NEW_PATH_Modelled_2022: The file contains annotation information for all the modeled structures, including structure names, modifications of CDR3 sequences, introduced substitutions, mutation order, and the original PDB templates
