What’s new?

Version 0.10 (2022-03-14)

This release brings experimental fNIRS suppot, improvements in coordinate frame handling, and various enhancements regarding MRI fiducials.

📝 Notable changes

• We now have experimental support for fNIRS data (SNIRF format). This is still super fresh, and the respective BIDS enhancement proposal (BEP) has not yet been finalized & accepted into the standard. However, we’re excitied to be able to do this first step towards fNIRS support!

• Numerous improvements have been added to enhance our support for various coordinate frames, including those that are not yet supported by MNE-BIDS. These changes are mostly relevant to iEEG users. Please see the detailed list of changes below.

• We have added support for storing and reading multiple anatomical landmarks (“fiducials”) for the same participant. This makes it possible, for example, to store different sets of landmarks for each recording session.

• It’s now possible to store Neuroscan (CNT) files with MNE-BIDS.

Detailed list of changes

🚀 Enhancements

• Add experimental support for fNIRS (SNIRF) files in mne_bids.write_raw_bids(), by Robert Luke (#406)

• Add support for CNT (Neuroscan) files in mne_bids.write_raw_bids(), by Yorguin Mantilla (#924)

• Add the ability to write multiple landmarks with mne_bids.write_anat() (e.g. to have separate landmarks for different sessions) via the new kind parameter, by Alexandre Gramfort (#955)

• Similarly, mne_bids.get_head_mri_trans() and mne_bids.update_anat_landmarks() gained a new kind parameter to specify which of multiple landmark sets to operate on, by Alexandre Gramfort and Richard Höchenberger (#955, #957)

• Add support for iEEG data in the coordinate frame Pixels; although MNE-Python does not recognize this coordinate frame and so it will be set to unknown in the montage, MNE-Python can still be used to analyze this kind of data, by Alex Rockhill (#976)

• Add an explanation in 08. Convert iEEG data to BIDS format of why it is better to have intracranial data in individual rather than template coordinates, by Alex Rockhill (#975)

• mne_bids.update_anat_landmarks() can now directly work with fiducials saved from the MNE-Python coregistration GUI or mne.io.write_fiducials(), by Richard Höchenberger (#977)

• All non-MNE-Python BIDS coordinate frames are now set to 'unknown' on reading, by Alex Rockhill (#979)

• mne_bids.write_raw_bids() can now write to template coordinates by Alex Rockhill (#980)

• Add mne_bids.template_to_head() to transform channel locations in BIDS standard template coordinate systems to head and also provides a trans, by Alex Rockhill (#983)

🧐 API and behavior changes

• mne_bids.update_anat_landmarks() will now by default raise an exception if the requested MRI landmarks do not already exist. Use the new on_missing parameter to control this behavior, by Richard Höchenberger (#957)

• mne_bids.get_head_mri_trans() now raises a warning if datatype or suffix of the provided electrophysiological mne_bids.BIDSPath are not set. In the future, this will raise an exception, by Richard Höchenberger`_(:gh:`969)

• Passing fs_subject=None to get_head_mri_trans() has been deprecated. Please pass the FreeSurfer subject name explicitly, by Richard Höchenberger`_ (#977)

• Corrupted or missing fiducials in head coordinates now raise an error instead of warning in mne_bids.write_raw_bids() by Alex Rockhill (#980)

🛠 Requirements

• MNE-BIDS now requires Jinja2 to work with MNE-Python 0.24.

🪲 Bug fixes

• Forcing EDF conversion in mne_bids.write_raw_bids() properly uses the overwrite parameter now, by Adam Li (#930)

• mne_bids.make_report() now correctly handles participant.tsv files that only contain a participant_id column, by Simon Kern (#912)

• mne_bids.write_raw_bids() doesn’t store age, handedness, and sex in participants.tsv anymore for empty-room recordings, by Richard Höchenberger (#935)

• When mne_bids.read_raw_bids() automatically creates new hierarchical event names based on event values (in cases where the same trial_type was assigned to different value``s in ``*_events.tsv), 'n/a' values will now be converted to 'na', by Richard Höchenberger (#937)

• Avoid DeprecationWarning in mne_bids.inspect_dataset() with the upcoming MNE-Python 1.0 release, by Richard Höchenberger (#942)

• Avoid modifying the instance of mne_bids.BIDSPath if validation fails when calling mne_bids.BIDSPath.update(), by Alexandre Gramfort (#950)

• mne_bids.get_head_mri_trans() now respects datatype and suffix of the provided electrophysiological mne_bids.BIDSPath, simplifying e.g. reading of derivaties, by Richard Höchenberger (#969)

• Do not convert unknown coordinate frames to head, by Alex Rockhill (#976)
