15 | biobb_flexserv NMARun 

16 | Wrapper of the Normal Mode Analysis tool from the FlexServ module. 

17 | Generates protein conformational structures using the Normal Mode Analysis (NMA) method. 

18 

19 Args: 

20 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). 

21 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/nma_run_out.log>`_. Accepted formats: log (edam:format_2330), out (edam:format_2330), txt (edam:format_2330), o (edam:format_2330). 

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

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

24 * **binary_path** (*str*) - ("diaghess") NMA binary path to be used. 

25 * **frames** (*int*) - (1000) Number of frames in the final ensemble 

26 * **nvecs** (*int*) - (50) Number of vectors to take into account for the ensemble generation 

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

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

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