AbstractFeatureSeries:
|
|
name: AbstractFeatureSeries
|
|
description: Abstract features, such as quantitative descriptions of sensory stimuli.
|
|
The TimeSeries::data field is a 2D array, storing those features (e.g., for
|
|
visual grating stimulus this might be orientation, spatial frequency and contrast).
|
|
Null stimuli (eg, uniform gray) can be marked as being an independent feature
|
|
(eg, 1.0 for gray, 0.0 for actual stimulus) or by storing NaNs for feature values,
|
|
or through use of the TimeSeries::control fields. A set of features is considered
|
|
to persist until the next set of features is defined. The final set of features
|
|
stored should be the null set. This is useful when storing the raw stimulus
|
|
is impractical.

description: Stores intervals of data. The timestamps field stores the beginning

(>0 value) or ended (<0 value). Different interval types can be represented
|
|
in the same series by using multiple key values (eg, 1 for feature A, 2 for
|
|
feature B, 3 for feature C, etc). The field data stores an 8-bit integer. This
|
|
is largely an alias of a standard TimeSeries but that is identifiable as representing
|
|
time intervals in a machine-readable way.

waveforms:
|
|
name: waveforms
|
|
description: Individual waveforms for each spike on each electrode. This is
|
|
a doubly indexed column. The 'waveforms_index' column indexes which waveforms
|
|
in this column belong to the same spike event for a given unit, where each
|
|
waveform was recorded from a different electrode. The 'waveforms_index_index'
|
|
column indexes the 'waveforms_index' column to indicate which spike events
|
|
belong to a given unit. For example, if the 'waveforms_index_index' column
|
|
has values [2, 5, 6], then the first 2 elements of the 'waveforms_index'
|
|
column correspond to the 2 spike events of the first unit, the next 3 elements
|
|
of the 'waveforms_index' column correspond to the 3 spike events of the
|
|
second unit, and the next 1 element of the 'waveforms_index' column corresponds
|
|
to the 1 spike event of the third unit. If the 'waveforms_index' column
|
|
has values [3, 6, 8, 10, 12, 13], then the first 3 elements of the 'waveforms'
|
|
column contain the 3 spike waveforms that were recorded from 3 different
|
|
electrodes for the first spike time of the first unit. See https://nwb-schema.readthedocs.io/en/stable/format_description.html#doubly-ragged-arrays
|
|
for a graphical representation of this example. When there is only one electrode
|
|
for each unit (i.e., each spike time is associated with a single waveform),
|
|
then the 'waveforms_index' column will have values 1, 2, ..., N, where N
|
|
is the number of spike events. The number of electrodes for each spike event
|
|
should be the same within a given unit. The 'electrodes' column should be
|
|
used to indicate which electrodes are associated with each unit, and the
|
|
order of the waveforms within a given unit x spike event should be in the
|
|
same order as the electrodes referenced in the 'electrodes' column of this
|
|
table. The number of samples for each waveform must be the same.
