Warning when opening .dv files in Fiji


I just installed updates to ImageJ (version 2.0.0-rc-69/1.52p) and am now getting a warning message popping up in the console every time I try to open a .dv image. The .dv image will open the message. It does not give this warning for tif images. I have never had this issue before.

The console shows this message for each .dv image:

Any ideas how to fix this issue to remove the warning? Thanks–

Hi Stephanie,

The warning is due to the fact that Bio-Formats has not been able to identify the lens ID in the metadata. This means that the Objective metadata will not be populated but otherwise the warning is harmless.

If you know the below values for that ID then we can correct that in a future patch release:

  • manufacturer
  • model
  • numerical aperture (NA)
  • magnification
  • immersion (Oil, Water, WaterDipping, Air, Glycerol, Multi or Other)
  • correction if applicable (UV, PlanApo, PlanFluor, SuperFluor, VioletCorrected, Achro, Achromat, Fluor, Fl, Fluar, NeoFluar, Fluotar, Apo, PlanNeofluar or Other)


Thanks so much for explaining the warning message- my images were obtained using the following:

Manufacturer: Applied Precision
Model: Deltavision Elite
Numerical Aperture: 1.40
Magnification: 100x
Immersion: Oil
Correction: the objective has UPlanSApo written on it

Thanks Stephanie, I have opened a PR (https://github.com/openmicroscopy/bioformats/pull/3411) to add this lens ID in the next patch release of Bio-Formats.

Awesome, thank you! I appreciate the help.

Hi @Stephanie,

Would you have a sample file with that lensID which we could use in our repository for future regression testing? If so you can upload it to https://www.openmicroscopy.org/qa2/qa/upload/
