  • Upload both (CSV and annotated image) to the Chemotion (if image was from Chemotion)

3. Upload to Chemotion​

If the image was originally loaded from the Chemotion:

  • The tool sends both the annotated image and CSV to the original Chemotion URL
Requirements

  • Image Source Restriction Only images loaded from the Chemotion support cloud upload. If you upload an image locally (i.e., not from the Chemotion), the annotated image cannot be uploaded back to the Chemotion.

  • CSRF Token A valid CSRF token must be available. This is handled internally by the system.
