14 | biobb_amber ParmedCpinUtil
15 | Wrapper of the `AmberTools (AMBER MD Package) parmed tool <https://ambermd.org/AmberTools.php>`_ module.
16 | Creates a cpin file for constant pH simulations from an AMBER topology file using parmed tool from the AmberTools MD package.
18 Args:
19 input_top_path (str): Input AMBER topology file. File type: input. `Sample file <https://github.com/bioexcel/biobb_amber/raw/master/biobb_amber/test/data/parmed/structure.solv.top>`_. Accepted formats: top (edam:format_3881), parmtop (edam:format_3881), prmtop (edam:format_3881).
20 output_cpin_path (str): Output AMBER constant pH input (CPin) file. File type: output. `Sample file <https://github.com/bioexcel/biobb_amber/raw/master/biobb_amber/test/reference/parmed/cln025.cpin>`_. Accepted formats: cpin (edam:format_2330).
21 output_top_path (str) (Optional): Output topology file (AMBER ParmTop). File type: output. `Sample file <https://github.com/bioexcel/biobb_amber/raw/master/biobb_amber/test/reference/parmed/cln025.cpH.prmtop>`_. Accepted formats: top (edam:format_3881), parmtop (edam:format_3881), prmtop (edam:format_3881).
22 properties (dic - Python dictionary object containing the tool parameters, not input/output files):
23 * **resnames** (*str*) - ("None") Residue names to include in CPIN file. Values: AS4, GL4, HIP, CYS, LYS, TYR.
24 * **igb** (*int*) - (2) Generalized Born model which you intend to use to evaluate dynamics or protonation state swaps. Values: 1, 2, 5, 7, 8.
25 * **system** (*str*) - ("Unknown") Name of system to titrate.
26 * **binary_path** (*str*) - ("cpinutil.py") Path to the cpinutil.py 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 * **sandbox_path** (*str*) - ("./") [WF property] Parent path to the sandbox directory.
30 * **container_path** (*str*) - (None) Container path definition.
31 * **container_image** (*str*) - ('afandiadib/ambertools:serial') Container image definition.
32 * **container_volume_path** (*str*) - ('/tmp') Container volume path definition.
33 * **container_working_dir** (*str*) - (None) Container working directory definition.
34 * **container_user_id** (*str*) - (None) Container user_id definition.
35 * **container_shell_path** (*str*) - ('/bin/bash') Path to default shell inside the container.
