15 | biobb_analysis CpptrajRgyr
16 | Wrapper of the Ambertools Cpptraj module for computing the radius of gyration (Rgyr) from a given cpptraj compatible trajectory.
17 | Cpptraj (the successor to ptraj) is the main program in Ambertools for processing coordinate trajectories and data files. The parameter names and defaults are the same as the ones in the official `Cpptraj manual <https://amber-md.github.io/cpptraj/CPPTRAJ.xhtml>`_.
19 Args:
20 input_top_path (str): Path to the input structure or topology file. File type: input. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/data/ambertools/cpptraj.parm.top>`_. Accepted formats: top (edam:format_3881), pdb (edam:format_1476), prmtop (edam:format_3881), parmtop (edam:format_3881), zip (edam:format_3987).
21 input_traj_path (str): Path to the input trajectory to be processed. File type: input. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/data/ambertools/cpptraj.traj.dcd>`_.

22 output_cpptraj_path (str): Path to the output analysis. File type: output. `Sample file <https://github.com/bioexcel/biobb_analysis/raw/master/biobb_analysis/test/reference/ambertools/ref_cpptraj.rgyr.dat>`_. Accepted formats: dat (edam:format_1637), agr (edam:format_2033), xmgr (edam:format_2033), gnu (edam:format_2033).

28 * **binary_path** (*str*) - ("cpptraj") Path to the cpptraj executable binary.
29 * **remove_tmp** (*bool*) - (True) [WF property] Remove temporal files.
30 * **restart** (*bool*) - (False) [WF property] Do not execute if output files exist.
