[ome-users] Issue with OMEXMLMetadataImpl.getImageAcquisitionDate()?

[Sebastien Besson (Staff)]

As a follow-up comment,

the acquisition date was always filled by Bio-Formats 5.0.x. As of Bio-Formats 5.1.x,
this field is now optional and only filled if it can be read from the metadata.

For more information/technical details, see:
- the announcement of the 5.1.0-m1 milestone, notably the model changes section:
  https://www.openmicroscopy.org/community/viewtopic.php?f=6&t=7655&p=14837
- https://github.com/openmicroscopy/bioformats/pull/1235 which allows null acquisition dates
- https://github.com/openmicroscopy/bioformats/pull/1264 which implements some code for
  handling this new functionality in various utilities (command-line tools, ImageJ/Fiji plugin)

Best,
Sebastien

Hi Aaron,

Using Bio-Formats 5.1.1 and getImageAcquisitionDate<http://downloads.openmicroscopy.org/bio-formats/5.1.1/api/ome/xml/meta/MetadataRetrieve.html#getImageAcquisitionDate(int)>, I can retrieve the Timestamp
for some sample images. Is your issue happening for a particular file format? If so would
it be possible to upload a sample file at https://www.openmicroscopy.org/qa2/qa/upload/?

Best,
Sebastien

Hi,
the method ome.xml.meta.OMEXMLMetadataImpl.getImageAcquisitionDate<https://ci.openmicroscopy.org/view/5.0/job/BIOFORMATS-5.0-latest/javadoc/ome/xml/meta/OMEXMLMetadataImpl.html#getImageAcquisitionDate(int)>(int imageIndex) seems to be always returning null in bioformats 5.1.1. The same call on the same files with 5.0.8 returns a valid timestamp.
