# Editing XML in an OME-TIFF

To edit the XML in an OME-TIFF file you can use tiffcomment, one of the Bio-Formats tools.

Note

The 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
