mne.io.anonymize_info

mne.io.anonymize_info(info, daysback=None, keep_his=False, verbose=None)[source]

Anonymize measurement information in place.

Warning

If info is part of an object like raw.info, you should directly use the method raw.anonymize() to ensure that all parts of the data are anonymized and stay synchronized (e.g., raw.annotations).

Parameters
infodict, instance of Info

Measurement information for the dataset.

daysbackint | None

Number of days to subtract from all dates. If None (default), the acquisition date, info['meas_date'], will be set to January 1ˢᵗ, 2000. This parameter is ignored if info['meas_date'] is None (i.e., no acquisition date has been set).

keep_hisbool

If True, his_id of subject_info will not be overwritten. Defaults to False.

Warning

This could mean that info is not fully anonymized. Use with caution.

verbosebool | str | int | None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Returns
infoinstance of Info

The anonymized measurement information.

Notes

Removes potentially identifying information if it exists in info. Specifically for each of the following we use:

  • meas_date, file_id, meas_id

    A default value, or as specified by daysback.

  • subject_info

    Default values, except for ‘birthday’ which is adjusted to maintain the subject age.

  • experimenter, proj_name, description

    Default strings.

  • utc_offset

    None.

  • proj_id

    Zeros.

  • proc_history

    Dates use the meas_date logic, and experimenter a default string.

  • helium_info, device_info

    Dates use the meas_date logic, meta info uses defaults.

If info['meas_date'] is None, it will remain None during processing the above fields.

Operates in place.
