12 | biobb_flexserv BDRun 

13 | Wrapper of the Browian Dynamics tool from the FlexServ module. 

14 | Generates protein conformational structures using the Brownian Dynamics (BD) method. 

15 

16 Args: 

17 input_pdb_path (str): Input PDB file. File type: input. `Sample file <https://github.com/bioexcel/biobb_flexserv/raw/master/biobb_flexserv/test/data/flexserv/structure.ca.pdb>`_. Accepted formats: pdb (edam:format_1476). 

18 output_log_path (str): Output log file. File type: output. `Sample file <https://github.com/bioexcel/biobb_flexserv/raw/master/biobb_flexserv/test/reference/flexserv/bd_run_out.log>`_. Accepted formats: log (edam:format_2330), out (edam:format_2330), txt (edam:format_2330), o (edam:format_2330). 

19 output_crd_path (str): Output ensemble. File type: output. `Sample file <https://github.com/bioexcel/biobb_flexserv/raw/master/biobb_flexserv/test/reference/flexserv/bd_run_out.crd>`_. Accepted formats: crd (edam:format_3878), mdcrd (edam:format_3878), inpcrd (edam:format_3878). 

20 properties (dict - Python dictionary object containing the tool parameters, not input/output files): 

21 * **binary_path** (*str*) - ("bd") BD binary path to be used. 

22 * **time** (*int*) - (1000000) Total simulation time (ps) 

23 * **dt** (*float*) - (1e-15) Integration time (ps) 

24 * **wfreq** (*int*) - (1000) Writing frequency (ps) 

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

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

27 * **sandbox_path** (*str*) - ("./") [WF property] Parent path to the sandbox directory.
