Dataset

Rodgers whisker object-recognition DANDI dataset

DANDI NWB release containing behavioral events, high-speed whisker video links, pose/contact annotations, and neural recordings from head-fixed mice performing tactile shape discrimination or shape detection tasks.

Access notes

Access through DANDI version 0.220904.1554. Each session has an NWB file and may link to external raw video files; the adapter reads the NWB trials table directly or a CSV/TSV export of the same fields, and treats video-derived whisker contacts as optional rich task variables rather than required core trial columns.

Data formats

  • Neurodata Without Borders (NWB)
  • external high-speed video files
  • DANDI archive assets
  • pose and whisker-contact annotations

Expected trial-table mapping

Canonical fields the harmonizer expects this dataset to populate.

Canonical field Source mapping
choice Left or right lick response.
correct Source outcome mapped to boolean correctness.
evidence_strength Object position or contact-feature summary, if treated as strength.
feedback Water reward for correct choices.
response_time Lick response latency relative to response-window opening.
session_id Session name from NWB filename.
stimulus_side none; object is sampled with one whisker field and choice is reported by lick side.
stimulus_value Shape class or object-present condition.
subject_id Mouse identifier from DANDI subject folder.
task_variables task rule, concave/convex/catch condition, object position, object approach time, whisker identity, touch times, video frame alignment, neural recording availability, and contact annotations.
trial_index Trial index from behavioral event table.

Caveats

  • The dataset mixes detection and discrimination task rules that may need separate slice records.
  • Video files are linked externally from NWB sessions, so local tests avoid requiring full video download.
  • The DANDI record reports CC0-1.0 for the dataset release; the associated paper is separately CC-BY-4.0.
