setOptions(self, in_0)	Sets options for loading/storing
setProgress(self, value)	Sets the current progress
startProgress(self, begin, end, label)
store(self, filename, map)	Stores a map in a MzData file

endProgress(self) → None

Ends the progress display

getLogType(self) → int

Returns the type of progress log being used

getOptions(self) → PeakFileOptions

Returns the options for loading/storing

isSemanticallyValid(self, filename: Union[bytes, str, String], errors: List[bytes], warnings: List[bytes]) → bool

Checks if a file is valid with respect to the mapping file and the controlled vocabulary

• errors – Errors during the validation are returned in this output parameter

• warnings – Warnings during the validation are returned in this output parameter

Raises

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

load(self, filename: Union[bytes, str, String], map: MSExperiment) → None

Loads a map from a MzData file

Parameters

• filename – Directory of the file with the file name

• map – It has to be a MSExperiment or have the same interface

Raises

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

Raises

Exception: ParseError is thrown if an error occurs during parsing

nextProgress(self) → None

Increment progress by 1 (according to range begin-end)

setLogType(self, in_0: int) → None

setOptions(self, in_0: PeakFileOptions) → None

Sets options for loading/storing

setProgress(self, value: int) → None

Sets the current progress

startProgress(self, begin: int, end: int, label: Union[bytes, str, String]) → None

store(self, filename: Union[bytes, str, String], map: MSExperiment) → None

Stores a map in a MzData file

Parameters

• filename – Directory of the file with the file name

• map – It has to be a MSExperiment or have the same interface

Raises
