Data upload

Upload recordings from Studies → Upload (/experiments/{id}/upload). Each upload creates one dataset.

Upload flow

1. Select files — drag-and-drop or browse
2. Review — confirm detected format, duration, sample rate, validation messages
3. Import — writes files to storage and creates the dataset record

For EDF files, pick the signal channel on the review step. If the file contains respiration, you can select a separate respiration channel (must differ from the ECG channel).

Supported formats

Modality	Format	Files	Notes
ECG	WFDB	.hea + .dat	Both required; same basename
ECG	CSV	Single .csv	Column 1 = time (s), column 2 = amplitude
ECG	EDF	.edf	Pick channel on review
RR intervals	rr_csv	Single .csv	Requires rr_ms column
PPG	CSV / WFDB / EDF	Per format rules	Detected as PPG signal type
Blood pressure	bp_csv	Single .csv	SBP/DBP columns + timestamps
Respiration	EDF / CSV	Channel or dedicated file	Used for RSA and respiration analysis

Validation rules

• WFDB uploads must include matching .hea and .dat files
• CSV time columns must be strictly increasing numeric values
• RR CSV must contain parseable rr_ms values
• EDF ECG and respiration channels cannot be the same index
• Very short series are rejected with a clear error message

After upload

The dataset appears on the study overview. Click it to open the dataset inspector and run the appropriate pipeline for its signal type.

RR-only datasets skip waveform preprocessing — go directly to Compute HRV.
