[ome-users] omeMeta.getPlaneExposureTime fails to grab correct exposure times

[Sebastien Besson (Staff)]

Hi Édouard,

Thanks for the support and reporting this issue. From your description, it sounds like a
bug while parsing the exposure time. Having access to sample data for us to reproduce
the issue would be the most useful at this point.

If your Nikon nd2 files are smaller than 2GB, you should be able to upload them at
http://qa.openmicroscopy.org.uk/qa/upload/. For larger files, we can provide you with the
credentials to a FTP server. Let us know what works best for you.

Best,
Sebastien

Hi guys,

I'm a PhD student from ESPCI, Paris, France. And first i'd like to say thanks for the awesome work with bioformats.

I use bioformats (up to date version) to analyze my nd2 files with MATLAB scripts. I'd like now to use the exposure time as a parameter. My images typically have 2 planes with varying exposure times.

I can grab the exposure times og both planes using metadata.get ; but then I have to deal with the unit and it's kind of not very elegant. I'd like to be able to use OME metadata. However,

omeMeta.getPlaneExposureTime(0,0).getValue()
omeMeta.getPlaneExposureTime(0,1).getValue()

give me the same exposure time, whereas it is clearly different.

Is there anything I can do to work around it? Or is it a bug?

I can provide with additional information upon request, as long as files.

Best,

Édouard
