14 | biobb_analysis GMXRms 

15 | Wrapper of the GROMACS rms module for performing a Root Mean Square deviation (RMSd) analysis from a given GROMACS compatible trajectory. 

16 | `GROMACS rms <http://manual.gromacs.org/current/onlinehelp/gmx-rms.html>`_ compares two structures by computing the root mean square deviation (RMSD), the size-independent rho similarity parameter (rho) or the scaled rho (rhosc). 

17 

18 Args: 

19 input_structure_path (str): Path to the input structure file. File type: input. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/data/gromacs/topology.tpr>`_. Accepted formats: tpr (edam:format_2333), gro (edam:format_2033), g96 (edam:format_2033), pdb (edam:format_1476), brk (edam:format_2033), ent (edam:format_1476). 

20 input_traj_path (str): Path to the GROMACS trajectory file. File type: input. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/data/gromacs/trajectory.trr>`_.

21 input_index_path (str) (Optional): Path to the GROMACS index file. File type: input. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/data/gromacs/index.ndx>`_. Accepted formats: ndx (edam:format_2033). 

22 output_xvg_path (str): Path to the XVG output file. File type: output. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/reference/gromacs/ref_rms.xvg>`_. Accepted formats: xvg (edam:format_2030).

24 * **xvg** (*str*) - ("none") XVG plot formatting. Values: xmgrace, xmgr, none. 

25 * **selection** (*str*) - ("System") Group where the rms will be performed. If **input_index_path** provided, check the file for the accepted values.

26 * **binary_path** (*str*) - ("gmx") Path to the GROMACS executable binary. 

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

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

29 * **container_path** (*str*) - (None) Container path definition.
