A subpackage for fetching data from online databases.

Each subpackage of the database package contains an interface for a specific database.

One function, all subpackages share, is the fetch() function. It will download one or multiple files that were specified via the function arguments (e.g. PDB ID) into the specified directory. The return value is the downloaded file name or a list of file names respectively.

If the file is only needed temporarily, they can be stored in a temporary directory by using biotite.temp_dir() or biotite.temp_file() as path name.


biotite.database.entrez A subpackage for downloading files from the NCBI Entrez database.
biotite.database.rcsb A subpackage for downloading files from the RCSB PDB.
