13 | biobb_pdb_tools Pdbchain 

14 | Modifies the chain identifier column of a PDB file. 

15 | This tool modifies the chain identifier column of a PDB file. It can be used to change the chain identifier of a PDB file or to remove the chain identifier from a PDB file. 

16 

17 Args: 

18 input_file_path (str): Input PDB file. File type: input. `Sample file <https://raw.githubusercontent.com/bioexcel/biobb_pdb_tools/master/biobb_pdb_tools/test/data/pdb_tools/1AKI.pdb>`_. Accepted formats: pdb (edam:format_1476). 

19 output_file_path (str): PDB file with selected modified chain. File type: output. `Sample file <https://raw.githubusercontent.com/bioexcel/biobb_pdb_tools/master/biobb_pdb_tools/test/reference/pdb_tools/ref_pdb_chain.pdb>`_. Accepted formats: pdb (edam:format_1476). 

20 properties (dic): 

21 * **chain** (*string*) - ('A') Modifies the chain identifier column of a PDB file. 

22 * **binary_path** (*str*) - ("pdb_chain") Path to the pdb_chain executable binary. 

23 * **remove_tmp** (*bool*) - (True) [WF property] Remove temporal files. 

24 * **restart** (*bool*) - (False) [WF property] Do not execute if output files exist.
