<div dir="ltr">Hi Susan,<br><br>Where exactly are you are seeing the metadata?<br><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>
