list_assemblies
#
- biotite.structure.io.pdbx.list_assemblies(pdbx_file, data_block=None)[source]#
List the biological assemblies that are available for the structure in the given file.
This function receives the data from the
pdbx_struct_assembly
category in the file. Consequently, this category must be present in the file.- Parameters:
- pdbx_fileCIFFile or CIFBlock or BinaryCIFFile or BinaryCIFBlock
The file object.
- data_blockstr, optional
The name of the data block. Default is the first (and most times only) data block of the file. If the data block object is passed directly to pdbx_file, this parameter is ignored.
- Returns:
- assembliesdict of str -> str
A dictionary that maps an assembly ID to a description of the corresponding assembly.
Examples
>>> import os.path >>> file = CIFFile.read(os.path.join(path_to_structures, "1f2n.cif")) >>> assembly_ids = list_assemblies(file) >>> for key, val in assembly_ids.items(): ... print(f"'{key}' : '{val}'") '1' : 'complete icosahedral assembly' '2' : 'icosahedral asymmetric unit' '3' : 'icosahedral pentamer' '4' : 'icosahedral 23 hexamer' '5' : 'icosahedral asymmetric unit, std point frame' '6' : 'crystal asymmetric unit, crystal frame'
