Behavior data
The behavior folder contains pickled dataframe objects with fish trajectories around playback events. (5s before playback, 7s after playback, 120fps).
65fish_nolla.zip Data on 65 female and male adult Danionella cerebrum without lateral line ablation.74fish_lla.zip Data on 74 female and male adult Danionella cerebrum after lateral line ablation.
Load like this (in python):
import pandas as pd
df = pd.read_pickle('65fish_nolla.zip')
To generate paper figures based on this data, see:

The subfolder sleap_model contains the fish skeleton, parameters, and the trained model that was used to track a single Danionella cerebrum in a 336 x 336 pixel recording, spanning a ~ 11 x 11cm field of view.
Micro CT data
PMA (phosphomolybdic acid)-stained, adult, male Danionella cerebrum.
Raw data
