Editing XML in an OME-TIFF ========================== To edit the XML in an OME-TIFF file you can use :command:`tiffcomment`, one of the Bio-Formats tools. .. note:: The :command:`tiffcomment` tool requires that the `ImageDescription` tag is present in the TIFF file and will error otherwise. To use the built in editor run: :: tiffcomment -edit sample.ome.tif To extract or view the XML run: :: tiffcomment sample.ome.tif To inject replacement XML into a file run: :: tiffcomment -set 'newmetadata.xml' sample.ome.tif
