[Feature request] Recognize ndx-events objects for event times raster plots?

[tuanpham96]

I got this error when I tried loading an AnnotatedEventsTable created with ndx-events.

View plugin not found: neurodata-item:/processing/ophys/events|AnnotatedEventsTable

It would be great if neurosift can recognize event_times column in event tables (types: LabeledEvents, AnnotatedEventsTable) created by ndx-events for raster plots

Hi @tuanpham96

Is there a dandiset that has this data type? That would make it easy for me to develop against. Otherwise, is there a way you can send me an example .nwb file for this feature?

I'm not certain whether there's an existing dandiset for this yet. Maybe @bendichter knows.

Here's an example NWB file I generated from modifying the example from ndx-events README

@tuanpham96

AnnotatedEventsTable is now supported.

You should now see the following:

which allows you to get two types of views

(a) A raster plot
(b) A table, with one row per unit

@magland An example of the LabeledEvents type can be found here: https://flatironinstitute.github.io/neurosift/?p=/nwb&url=https://dandiarchive.s3.amazonaws.com/blobs/80d/c44/80dc4460-7652-4b88-97ce-69a7e8be5d60&tab=neurodata-item:/processing/behavior/RewardEventsLinearTrack|LabeledEvents

Thanks @CodyCBakerPhD.

It appears that LabeledEvents does not have an event_times dataset. It has a timestamps dataset.

How would you expect LabeledEvents to be displayed? Raster plot with only one row?

[CodyCBakerPhD]

It appears that LabeledEvents does not have an event_times dataset. It has a timestamps dataset.

LabeledEvents have data (non-unique integers indexing the labels), labels (list of unique strings), and timestamps (equal to the length of data)

https://pypi.org/project/ndx-events/

How would you expect LabeledEvents to be displayed? Raster plot with only one row?

I'd say a general strategy for this would be a raster whose number of 'units' (columns or Y axis) is the number of unique labels

[tuanpham96]

@magland thanks for this! I tested and it looks fine for the AnnotatedEventsTable for the time being. It'd be great to also support LabeledEvents as well, but since you already opened another issue., should I close this one?

[magland]

Glad that's working. Yes, I'll close this issue and we can follow up with #92.
