Because our platform only accepts PDB files with one single chain, query antigen should be labeled in single chain with unique residue numbers.
This program is used to make unique numerical identifiers for residues. For example, PDB file with residue ids marked as "100", "100A", "100B", "101" will be transformed into "100", "101", "102", "103".
This program can be used to identify epitope residues in antigen-antibody complexes. The epitope residues are defined as those with least atom towards antibody with certain distance.Note: only files with single one chain for antigen can be accepted (chains for antibody can be more). Multiple antigen chains can be merged into one by above tool.
