| biobb_flexserv PCZunzip
| Wrapper of the pcaunzip tool from the PCAsuite FlexServ module.
| Uncompress Molecular Dynamics (MD) trajectories compressed using Principal Component Analysis (PCA) algorithms.
Args:
input_pcz_path (str): Input compressed trajectory. File type: input. `Sample file <https://github.com/bioexcel/biobb_flexserv/raw/master/biobb_flexserv/test/data/pcasuite/pcazip.pcz>`_. Accepted formats: pcz (edam:format_3874).
output_crd_path (str): Output uncompressed trajectory. File type: output. `Sample file <https://github.com/bioexcel/biobb_flexserv/raw/master/biobb_flexserv/test/reference/pcasuite/traj.crd>`_. Accepted formats: crd (edam:format_3878), mdcrd (edam:format_3878), inpcrd (edam:format_3878), pdb (edam:format_1476).
properties (dict - Python dictionary object containing the tool parameters, not input/output files):
* **binary_path** (*str*) - ("pcaunzip") pcaunzip binary path to be used.
* **verbose** (*bool*) - (False) Make output verbose
* **pdb** (*bool*) - (False) Use PDB format for output trajectory
* **remove_tmp** (*bool*) - (True) [WF property] Remove temporal files.
* **restart** (*bool*) - (False) [WF property] Do not execute if output files exist.
* **sandbox_path** (*str*) - ("./") [WF property] Parent path to the sandbox directory.
* **container_path** (*str*) - (None) Container path definition.
* **container_image** (*str*) - ('afandiadib/ambertools:serial') Container image definition.
* **container_volume_path** (*str*) - ('/tmp') Container volume path definition.
* **container_working_dir** (*str*) - (None) Container working directory definition.
* **container_user_id** (*str*) - (None) Container user_id definition.
* **container_shell_path** (*str*) - ('/bin/bash') Path to default shell inside the container.
Examples:
This is a use example of how to use the building block from Python::
from biobb_flexserv.pcasuite.pcz_unzip import pcz_unzip
prop = {
'pdb': False
}
pcz_unzip( input_pcz_path='/path/to/pcazip_input.pcz',
output_crd_path='/path/to/pcazip_traj.crd',
properties=prop)
