biobb_structure_utils is the Biobb module collection to perform basic manipulations on 3d structures.

Project description



Biobb_structure_utils is the Biobb module collection to modify or extract information from a PDB structure file, such as pulling out a particular model or chain, removing water molecules or ligands, or renumbering or sorting atoms or residues. Biobb (BioExcel building blocks) packages are Python building blocks that create new layer of compatibility and interoperability over popular bioinformatics tools. The latest documentation of this package can be found in our readthedocs site: latest API documentation.


v3.7.0 2021.3


Using PIP:

Important: PIP only installs the package. All the dependencies must be installed separately. To perform a complete installation, please use ANACONDA, DOCKER or SINGULARITY.



  • Installation:

  • Usage:

      docker run <command>


MacOS users: it's strongly recommended to avoid Singularity and use Docker as containerization system.

  • Installation:

      singularity pull --name biobb_structure_utils.sif shub://bioexcel/biobb_structure_utils
  • Usage:

      singularity exec biobb_structure_utils.sif <command>
