dbPreprocessing()

Overload:

dbPreprocessing(self, db_path: Union[bytes, str, String], save: bool) → None

Calculates tryptic peptide masses of a given database and stores masses and peptide sequences

Parameters

• db_path – Path to database file (fasta)

• save – Flag if preprocessing should be stored

Raises

Exception: FileNotFound is thrown if the file could not be found

Raises

Exception: UnableToCreateFile if preprocessing file can’t be written

Overload:

dbPreprocessing(self, db_path: Union[bytes, str, String], rt_model_path: Union[bytes, str, String], dt_model_path: Union[bytes, str, String], save: bool) → None

Calculates tryptic peptide masses of a given database and stores masses and peptide sequences

Parameters

• db_path – Path to database file (fasta)

• rt_model_path – Path to the retention time model

• dt_model_path – Path to the detectability model

• save – Flag if preprocessing should be stored

Raises

Exception: FileNotFound is thrown if the file could not be found

Raises

Exception: UnableToCreateFile if preprocessing file can’t be written
