<p class="MsoNormal">This is in my mind a bug in filters.ferry. There's no reason for it not to create multiple desitnation dimensions from a source dimension, or to create one from nothing.<o:p></o:p></p>

<p class="MsoNormal">P.S. - Although it's kludgy, you can create a dimension by reading in a text file in addition to your tiff file. Just create a text file that has nothing in it but a header line. You can stick whatever dimensions you want in there. In
your case, the file can just contain the text "Classification". So your pipeline would look like:<o:p></o:p></p>
