Score A-
Score A, close to the B boundary
Favourable spindle morphology pattern. The detected spindle appears well-organized and clearly defined.

Finding
Spindle not detected
An oocyte was found in this clip but no spindle could be located, so no score was assigned. This is a finding about the clip, not a system error. Re-focus on the spindle region and record again.

Finding
Oocyte not detected
No oocyte could be located in this clip, so no score was assigned. This is a finding about the clip, not a system error. Check that the oocyte is centred and in focus, then record again.

⚠

Analysis incomplete

The system could not detect and analyze a meiotic spindle in this video.

  • Center the oocyte in the field of view
  • Verify optimal focus and lighting
  • Enable polarized light mode
  • Record 10-30 seconds of stable video
  • Minimize stage movement during capture
33
Spindle not detected

A finding, not an error, and not charged. Only the oocyte crop is kept (View in the history). Re-focus and record again.

34
Oocyte not detected

A finding, not charged, nothing stored. Centre and focus the oocyte, then record again.

35
Failure (passive page)

The analysis did not complete; not charged. If it repeats while the server looks fine, use the support block (4).

36
Analysis incomplete (active page)

No spindle could be measured, or the server did not answer. Follow the tips and record again.
