| Anomaly | Severity | Effect on the Fixed Pipeline |
|---|---|---|
| preprocessed deposit | warn | The recording is documented as background-subtracted, 3 × 3 spatially binned, low-pass filtered at 100 Hz, drift-removed, and normalized before deposit. The fixed pipeline can be run, but its Gaussian phase smoothing and baseline removal are being applied on top of prior filtering and drift correction of unknown total effect; amplitude, noise, and SNR-related interpretations should not be treated as raw-camera measurements. |
| polarity transformed relative to dye | warn | RH237 normally decreases fluorescence on depolarization, but the deposited data measure as non-inverted. The pipeline should orient activation from measured polarity rather than dye expectation, so activation analysis is not expected to be made wrong if measured polarity is used. |
The recording matches the protocol at the level needed to use the fixed parameter set: it is a rat whole-heart ventricular-fibrillation optical-mapping recording from the referenced public dataset, and no protocol field conflicts with the recording facts. The recording frame rate is 1000 Hz from deposit metadata; the protocol does not prescribe a different frame rate, and with the fixed baseline window the measured dominant rhythm is not in the caveated regime where the baseline window is shorter than about 1.5 cycles. The run should proceed, but the reader must treat the data as preprocessed rather than raw because prior binning, low-pass filtering, drift removal, and normalization affect the meaning of further smoothing, baseline correction, amplitude, and noise estimates.
Inspector
This is a preprocessed ex vivo Langendorff rat whole-heart VF optical-mapping recording under 80 nM rotigaptide, recorded at 1000 Hz according to the deposit; that agrees with the value already on record. The 128 × 80 deposited image size matches both the deposit and the linked paper, and the paper also reports 1000 frames/s. The data have documented preprocessing before deposit, including background subtraction, 3 × 3 spatial binning, 100 Hz low-pass filtering, drift removal, and normalization, so analyses should not treat them as raw camera counts. Measured polarity is consistently non-inverted even though RH237 normally dims on depolarization, so use measured polarity for orientation. No acquisition-log or detected event annotations are available for this recording.
| Measurement | Value | Method, Caveat |
|---|---|---|
| SNR, median (p10–p90) | 18.8 (13.9–25.9) | assumes white noise; on temporally smoothed deposits noise is underestimated and SNR inflated |
| Mask coverage | 50.9%, 5216 of 10240 px | depositor NaN mask (frame 0) |
| Polarity | blocks 7, inverted False, blocks agreeing 7, median dvdt skew 0.08132843673229218 | sign of median per-pixel skew of dV/dt, baseline-corrected (121 frames) |
| Drift / bleaching | baseline change -0.0108, vs beat amplitude -0.0979, slow range 0.162, trend, Spearman -0.356 | running median (381 frames) of the tissue-mean raw signal; steps from events (light, rhythm change) and depositor normalization or drift removal change or erase the baseline; bleaching cannot be separated from them here |
| Prior processing | unit range, non integer, nan mask partial, temporal smoothing, spatial smoothing | deposit checks |
| Dominant cycle by block, frames | 0–1000: 29.4, 1000–2000: 28.6, 2000–3000: 28.6, 3000–3800: 25.0 |
| Concern | Severity | Detail |
|---|---|---|
| preprocessed deposit | warn | The deposit is not raw camera data: it is documented as background-subtracted, spatially binned, low-pass filtered, drift-removed, and the publication says normalized. Analyses requiring raw fluorescence/counts or unfiltered noise statistics would be misleading. |
| polarity transformed relative to dye | warn | RH237 normally dims on depolarization, but measured polarity is non-inverted with 7/7 blocks agreeing. The depositor appears to have flipped or transformed the sign; the pipeline should orient from the measured polarity, so this is not expected to make activation analysis wrong if handled. |
| SNR depends on preprocessing | info | Median SNR is high, but documented temporal filtering and detected temporal smoothing can inflate the SNR estimate by reducing apparent frame-to-frame noise. |
| reference thresholds provisional | info | No frame-rate inference was needed because the deposit states 1 kHz. Any conclusions from automated processing flags and provisional rhythm/reference-rate tools should be treated as not yet domain-scientist reviewed. |
Inspector report 2026-10-27 20:27 UTC, model openai:gpt-5.5, provisional. Median per-pixel SNR over tissue is 18.818067017408147, with p10 = 13.893293967898506 and p90 = 25.936276941781777 over 3000 frames. The SNR tool cautions that temporal smoothing underestimates noise and inflates SNR; that caveat applies because low-pass filtering is documented and temporal smoothing was detected. The tissue mask contains 5216 pixels out of 10240 total pixels, coverage 0.509375. The mask source is a depositor NaN mask in frame 0; frame 0 has 5024 NaN pixels. No stored events were returned, no acquisition log is present, and no detected light transitions or image baseline-step events were returned. Therefore there are no event frames to interpret for this recording. If events are later added, image-only baseline steps should be treated only as fluorescence changes unless a log shows a light transition at the same frame. The tissue-mean slow baseline, measured with a 381-frame running median, changes from 0.4981755316257477 to 0.48741528391838074, a change of -0.010760247707366943, equal to -0.09788043294092134 of the p5–p95 beat amplitude. Slow baseline range is 0.1622154712677002 and Spearman trend is -0.3557674750723145. Because the deposit documents drift removal and normalization, residual bleaching cannot be separated from preprocessing effects here.

| pipeline.check.anomalies[0].effect_on_analysis | The recording is documented as background-subtracted, 3 × 3 spatially binned, low-pass filtered at 100 Hz, drift-removed, and normalized before deposit. The fixed pipeline can be run, but its Gaussian phase smoothing and baseline removal are being applied on top of prior filtering and drift correction of unknown total effect; amplitude, noise, and SNR-related interpretations should not be treated as raw-camera measurements. | The deposited data are already background-subtracted, spatially binned, low-pass filtered, drift-removed, and normalized, so the fixed pipeline will not be operating on raw camera counts. The protocol Gaussian phase blur and other steps are applied on top of prior filtering/binning of known description but unknown effective total filtering; amplitude/noise-dependent interpretations should be treated cautiously. |

The protocol is for a rat whole-heart public reference ventricular-fibrillation recording, and the recording facts match that setting; the protocol does not specify an indicator, frame rate, pixel size, or image size that would be contradicted by the recording. The frame rate is 1000 Hz from deposit metadata, and with baseline_frames = 121 the dominant rhythm estimate for the analysed window gives a baseline window of 4.88 cycles, so the fixed baseline setting is not obviously inappropriate on the stated cycle-length criterion. The main cautions are not protocol mismatches but data provenance issues: the deposit is already preprocessed, and its measured polarity is transformed relative to the usual RH237 dye polarity. |
