[electrophysiology_browser] EventPanel 2.0 | HED Endorsement | Channels Support (EEG-BIDS) | Miscellaneous Features

[jeffersoncasimir]

This PR adds the latest EEG features from EEGNet.

Notably, this includes a major overhaul to the Event Panel and adds the ability to "Endorse" HED tags - as well as caveat and/or comment. Filter/search also added.

Additional features to support event channels: i.e. Events can be created/tagged for subsets of channels.

• Toggle selection from montage view
• Toggle selection from signals
• time segment highlighting is now channel-based (all unless defined)

Downloadable dynamic events.json file (Dataset Tag Manager) updates itself after new tags are added/used.

Screenshots:

@jeffersoncasimir how about adding to the PR description something like : generates updated and downloadable BIDS-compliant events.json based on current tags, via the Dataset Tag Manager submodule

[christinerogers]

Note also: I edited the PR description for a bit more clarity esp for the release notes.

• HED link is down https://www.hed-resources.org/en/latest/index.html
  maybe just link to HEDtags.org?

@jeffersoncasimir want to let me know for Monday if you need more info to reproduce these?

where I tested it on https://jcasimir-test-27.loris.ca/electrophysiology_browser/sessions/2161?outputType=raw:

• Dataset Tag manager button not visible - not testable.
• Tagged by / Endorsed by / Caveat By -> these lists are empty, feature is not usable. Is a patch / something else missing?
• Adding a second HED Artifact tag doesn't work: Message: fill all the other tags first -- also if it's a warning /error it shouldn't be green.

Did more testing on : https://jcasimir-test-27.loris.ca/electrophysiology_browser/sessions/167?outputType=raw

• Adding any HED Artifact tag doesn't work
• Endorsement problem w keystrokes: If I use the key strokes (^ C or M) after clicking in the 3rd HED tag, it changes the 1st HED tag visible. Please disable and remove the hover text regarding keystrokes if it can't be fixed for this release
• can't undo my own Caveat.
• tried to remove 2 tags added by Data authors. It showed me the X next to each orange tag (suggesting I could) so I clicked. then clicked Submit. got an error message but no details. The orange tags disappear and the submit button greyed out, but when i navigate elsewhere I am asked to confirm that i will lose changes. If i refresh the orange tags are back (delete failed)
• from the HEd endorsement panel -- the edit pencil likewise suggests I can edit tags but I don't have that permission as admin. either the messaging or the behaviour needs clarification.
• unclear how to add a tag only to specific channels, without changing the channel scope of all tags. When I go to add a tag for only a few channels it changes the channels on all the existing tags added by Data Authors which are otherwise uneditable (or so it seems)

@christinerogers please retest and amend the list to remove items that were due to the timing in which you were testing (like a crucial button not being visible). You apparently caught my testing VM in a window where I was rebuilding to test another PR. Make sure to use the OTT recordings and not the random other one.

Please note, an instance-level HED tag must be manually added (or present in the recording, which is not the case here) in order to appear on the list of HED endorsements. To test the (non-DTM) HED endorsement feature, you need to manually add a HED tag first.

Also, some of these points are not realistically fixable for the release or are known by the EEGNet team and have a corresponding open issue. If any changes are requested, please formulate them as such.

Followup PR can include:

• configurable HED Endorsement (useHEDendorsement Yes/No) since some LORISes may not use endorsement
• maybe also configurable HED support/visibility ; since some LORISes may not want users to add tags (useHEDtags config; and/or permission to add, which would also need to be project-specific)
• documentation on these features (e.g. module markdown, changelog)
• note if above configs are added, help text displayed should also be governed by this config

• Is it normal there are no all types?

• I think the link column can be removed from the csv download:
  data-2025-11-11T14_11_04.564Z.csv

• Broken link:

• When is this button available? It's always greyed out for me.

• I am getting a 500 error when downloading events file at URL: https://jcasimir-test-27.loris.ca/electrophysiology_browser/events?physioFileID=4&filePath=bids_imports/Face13_BIDSVersion_1.1.0/sub-OTT176/ses-V1/eeg/sub-OTT176_ses-V1_task-faceO_events.tgz
• Same for all files download

What is "tab re-open bug (json)"?

I'm not sure if this works since session_cache_limiter has already been called, but the correct way to add headers is to add the header to the ResponseInterface returned using PSR7
