Data Release - Pilot Dataset
The IBL has released a handful of pilot datasets that are available for download through ONE.
How to browse the datasets
If you first want to quickly view and browse what datasets are in a recording session, you can easily do so in a web browser via this Flatiron web page.
Generally speaking, a single recording session fits into a folder, which name is characterised by: it’s lab name / a folder Subjects / the name of the subject (i.e. the mouse nickname) / the date / the session number.
A lab can host multiple subjects, e.g. the Churchland lab hosts
There can be multiple sessions done in one day per subject, in such case the number of session
001would increase to
Sometimes, the valuable data is found only in a later session in the day (in the case of a restart for example), so it is not uncommon to see sessions for which only the
003folder is saved for example.
Neuropixels pilot datasets
Specifically, the Neuropixels pilot datasets are in the folders:
Taking the session from mainenlab/Subjects/ZM_2240/2020-01-21/001/ as example, the following subfolders will contain:
alf/: The extracted data, to be used in analysis.
logs/: logged information
raw_behavior_data/: The raw behavior data (events that occur during a trials)
raw_ephys_data/: The raw ephys data (in this case, Neuropixels data)
raw_passive_data/: The raw passive data (events that occur during the replay of task stimuli)
raw_video_data/: The raw video data
spike_sorters/: The raw processing output data for each spike sorter used
alf/ folder notably contains:
the probe folder (
probe01/), in which are the extracted output of the spike sorting to be used for analysis
the extracted behavior trials data
the extracted DLC data (for each camera used, here
the extracted wheel data
the extracted passive protocol data
One probe folder, e.g.
can contain the output of multiple spike sorters. In this case, it contains a first spike sorter output directly into the
folder itself (see e.g. the
cluster datasets), and a secondary version under a subfolder
(here the subfolder named
The size of each dataset can be easily viewed under the
Size column in the web browser. For example,
the raw vide data
is particularly heavy (several GB). In this specific case, you can view the raw video data in the browser by clicking on it,
