13 | biobb_chemistry AcpypeConvertAMBERtoGMX
14 | This class is a wrapper of `Acpype <https://github.com/alanwilter/acpype>`_ tool for the conversion of AMBER topologies to GROMACS.
15 | Acpype is a tool based in Python to use Antechamber to generate topologies for chemical compounds and to interface with others python applications like CCPN or ARIA. `Visit the official page <https://github.com/alanwilter/acpype>`_.
17 Args:
18 input_crd_path (str): Path to the input coordinates file (AMBER crd). File type: input. `Sample file <https://raw.githubusercontent.com/bioexcel/biobb_chemistry/master/biobb_chemistry/test/data/acpype/acpype.coords.inpcrd>`_. Accepted formats: inpcrd (edam:format_3878).
19 input_top_path (str): Path to the input topology file (AMBER ParmTop). File type: input. `Sample file <https://github.com/bioexcel/biobb_chemistry/raw/master/biobb_chemistry/test/data/acpype/acpype.top.prmtop>`_. Accepted formats: top (edam:format_3881), parmtop (edam:format_3881), prmtop (edam:format_3881).
20 output_path_gro (str): Path to the GRO output file. File type: output. `Sample file <https://github.com/bioexcel/biobb_chemistry/raw/master/biobb_chemistry/test/reference/acpype/ref_acpype.amber2gmx.gro>`_. Accepted formats: gro (edam:format_2033).
21 output_path_top (str): Path to the TOP output file. File type: output. `Sample file <https://github.com/bioexcel/biobb_chemistry/raw/master/biobb_chemistry/test/reference/acpype/ref_acpype.amber2gmx.top>`_. Accepted formats: top (edam:format_3880).
22 properties (dic - Python dictionary object containing the tool parameters, not input/output files):
23 * **basename** (*str*) - ("BBB") A basename for the project (folder and output files).
24 * **binary_path** (*str*) - ("acpype") Path to the acpype executable binary.
25 * **remove_tmp** (*bool*) - (True) [WF property] Remove temporal files.
26 * **restart** (*bool*) - (False) [WF property] Do not execute if output files exist.
27 * **container_path** (*str*) - (None) Container path definition.
28 * **container_image** (*str*) - ('acpype/acpype:2022.7.21') Container image definition.
29 * **container_volume_path** (*str*) - ('/tmp') Container volume path definition.
30 * **container_working_dir** (*str*) - (None) Container working directory definition.
31 * **container_user_id** (*str*) - (None) Container user_id definition.
32 * **container_shell_path** (*str*) - ('/bin/bash') Path to default shell inside the container.
34 Examples:
35 This is a use example of how to use the building block from Python::
