16 | biobb_analysis CpptrajBfactor
17 | Wrapper of the Ambertools Cpptraj module for calculating the Bfactor fluctuations of a given cpptraj compatible trajectory.
18 | 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>`_.
20 Args:
21 input_top_path (str): Path to the input structure or topology file.

Accepted formats: top (edam:format_3881), pdb (edam:format_1476), prmtop (edam:format_3881), parmtop (edam:format_3881), zip (edam:format_3987).
22 input_traj_path (str): Path to the input trajectory to be processed.
