MAXIT assists in the processing and curation of macromolecular structure data. MAXIT can: - Read and write PDB and mmCIF format files, and translate between file formats. - Perform consistency checks on coordinates, sequence, and crystal data. - Automatically construct, transform, and merge information between formats - Align residue numbering in the coordinates with the sequence - Reorder and rename atoms in standard and nonstandard residues and ligands according to the Chemical Component Dictionary - Assign ligands the same chain IDs as the adjacent polymers - Detect missing or additional atoms
