Files & exports

Where data are stored

Files › On My iPhone › RodentLimb › RodentLimb › Sessions. One folder per session:

File	Content
session.json	Subject, group, notes, assay, parameters, calibration, label edits
video.mov / .mp4	Copy of the imported video
pose.plist	Keypoints of every frame (binary property list)
result.json	Latest analysis
skeleton.mp4	Only if Also render skeleton video was on

Session export

All files start with <subject>_<ASSAY> (ASSAY = TST, CYL or GAIT). All text is English.

…_summary.csv

Long format with columns field, value, unit: session metadata (subject, group, assay, video, created, fps, duration_s, model, model_version, notes), then every measure by key, then the notes (note_info, note_warning, note_error).

Tail suspension

• …_immobility_bouts.csv: bout, start_s, end_s, duration_s, overlaps_window
• …_per_minute.csv: minute, immobility_s

Cylinder

• …_contacts.csv: event, onset_s, offset_s, rear, auto_label, final_label, edited, counted. Labels are left, right, both or ignore.

Gait

• …_strides.csv: paw, start_s, end_s, stride_s, stance_s, swing_s, duty, stride_length_<unit>, speed_<unit>_per_s (unit = cm or BL). Use the per-stride speed for speed-adjusted statistics.
• …_footprints.csv: paw, strike_s, x_px, y_px

…_methods.txt

A methods paragraph with your parameter values and the references for the assay.

…_pose.csv (optional)

frame, time_s, box_confidence, then <keypoint>_x, <keypoint>_y, <keypoint>_confidence for L_fore_paw, L_hind_paw, R_fore_paw, R_hind_paw, tail_base, nose, mouth. Coordinates are pixels in the displayed (rotation-corrected) frame, with the origin at the top left. Missing points have empty x/y.

Group export

From the Data tab (Select › Export CSV): one file per assay, RodentLimb_<ASSAY>_<n>_sessions_<date>.csv. One row per session: subject, group, video, created, status, then one column per measure as key [unit].

Measure keys

The keys are stable across versions, so scripts can rely on them. Examples: immobility_s, immobility_pct, latency_s, contra_use_pct, asymmetry_pct, stride_len_hind, duty_hind, bos_hind, ref_stride_len_bl, phase_LH_RH, pattern_trot_pct, nose_lateral_amp_bl. Each assay page lists its measures.
