rainbow.read

read(path, prec=0, hrms=False, requested_files=None, telemetry=False)[source]

Reads a chromatogram data directory. Main method of the package.

Increasing the precision may drastically increase memory usage for larger files. Specifying a higher precision mainly affects the parsing of MS data, because intensities are summed within the given precision for each ylabel.

Max precision available for Agilent MS data is 1.

Max precision recommended for Waters MS data is 3.

Agilent HRMS parsing may be slow. Set the flag to enable it.

For Agilent .dx archives, instrument telemetry traces (e.g. pressure, temperature) are skipped unless the telemetry flag is set.

Parameters:

  • path (str) – Path of the directory.

  • prec (int, optional) – Number of decimals to round ylabels.

  • hrms (bool, optional) – Flag for Agilent HRMS parsing.

  • requested_files (list, optional) – List of filenames to parse.

  • telemetry (bool, optional) – Flag for Agilent .dx telemetry traces.

Returns:

DataDirectory representing the directory.
