| biobb_io StructureInfo
| This class is a wrapper for getting all the available information of a structure from the Protein Data Bank.
| Wrapper for the `MMB PDB mirror <https://mdb-login.bsc.es/api/>`_ for getting all the available information of a structure from the Protein Data Bank.
Args:
output_json_path (str): Path to the output JSON file with all the structure information. File type: output. `Sample file <https://github.com/bioexcel/biobb_io/raw/master/biobb_io/test/reference/api/ref_str_info.json>`_. Accepted formats: json (edam:format_3464).
properties (dic - Python dictionary object containing the tool parameters, not input/output files):
* **pdb_code** (*str*) - (None) RSCB PDB structure code.
* **remove_tmp** (*bool*) - (True) [WF property] Remove temporal files.
* **restart** (*bool*) - (False) [WF property] Do not execute if output files exist.
* **sandbox_path** (*str*) - ("./") [WF property] Parent path to the sandbox directory.
Examples:
This is a use example of how to use the building block from Python::
from biobb_io.api.structure_info import structure_info
prop = {
'pdb_code': '2vgb'
}
structure_info(output_json_path='/path/to/newStructure.sdf',
properties=prop)
