<div dir="ltr">Hi Susan,<br><br>Sorry for the delay in my reply. I am not sure why CreationDate isn't showing up in OMERO. In the course of investigating it, though, we have fixed a bug in the DateTime parsing for TIFF files that caused some datestamps to be parsed incorrectly. The latest trunk build of Bio-Formats, available from the web site at <a href="http://www.loci.wisc.edu/ome/formats-download.html">http://www.loci.wisc.edu/ome/formats-download.html</a>, contains the fix.<br>
<br>Unfortunately, OMERO will not contain the bugfix until its next release, but you can at least verify that the datestamps are being parsed and standardized properly with your TIFF files.<br><br>If you use the Bio-Formats command line tools (<a href="http://www.loci.wisc.edu/ome/formats-tools.html">http://www.loci.wisc.edu/ome/formats-tools.html</a>), you can verify it using the showinf tool:<br>
<br>showinf myFile.tif -nopix -omexml<br><br>This will parse your TIFF, dump the metadata key/value pairs (including "DateTime" if present) to the console, and then dump the standardized block of OME-XML, which should contain a CreationDate element beneath the Image element. OMERO is supposed to be using the value of this element -- if not, it's likely a bug in OMERO.<br>
<br>As I mentioned before, you can also check your TIFFs using ImageJ. The latest trunk build contains a new "Display OME-XML metadata" option as part of the Bio-Formats Importer plugin, which will show the OME-XML tree in its own window.<br>
<br>If you don't see CreationDate being populated properly, let us know and we will fix it. However, if the problem is OMERO-specific, I'll have to defer to the OMERO guys on possible causes.<br><br>-Curtis<br><br>

<div>Curt, I am using the LOCI Plugin with ImageJ and that's where I see the DateTime value. My question is why isn't CreationDate showing up as a Property in either OME or OMERO.insight for that same image. That would be an important piece of annotation to be shown by default in your servers, so that researchers could use it to distinguish between many similar images.<div>

<br>Are you using Bio-Formats in ImageJ? If so, are you checking the "Display metadata in results window" option? Please note that the metadata displayed there is in the file's original format, and not standardized to OME.<br>
<br>The "DateTime" key is a TIFF-specific piece of metadata corresponding to the TIFF's DateTime field (value 306). It will only be displayed if a DateTime IFD entry was present in the TIFF file.<br><br>However, CreationDate is a required field under Image in OME, and Bio-Formats guarantees that it will be populated one way or another. In the case of TIFF, any given DateTime will be saved as the CreationDate. If no DateTime is present, the system's current date and time is used to populate the CreationDate (this is actually the default for all supported file formats).<br>
<br>Right now, you can view the standardized OME metadata in ImageJ by choosing "Data Browser" for "View stack with" in the Bio-Formats Importer Options, and then clicking the Metadata button when the window pops up. You should see another window containing a colored XML tree structure, with a <CreationDate> node beneath the <Image> node in the tree.<br>

Hi,<br> <br> I'm surprised that Creation Date is not a piece of metadata about an<br> imported image (they're using tif images because their zvi images are<br> not working properly at this time). It seems that ImageJ knows<br>
_something_ about a DateTime (although the units of such is a mystery<br> to me). Any comments on that, since it is a very important property<br> of images for my users.<br> <br> Thanks.<br> Susan<br> _______________________________________________<br>
