But this would be quite a lot of work.</div><div><br></div><div>One alternative is for your users to draw rectangle ROIs on their big images in Insight </div><div>(ROIs of 3000 x 3000 or less) then use the script: </div><div>util script > Images From ROIs </div><div>to create new images based on those regions. These can then be imported into OMERO.figure.</div><div><br></div><div> Hope that helps,</div><div><br></div><div> Will.</div><div><br></div><div><br></div><div><br><div><div>On 29 Oct 2014, at 17:32, Christophe TREFOIS <<a href="mailto:christophe.trefois@uni.lu">christophe.trefois@uni.lu</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="FR-BE" link="#0563C1" vlink="#954F72" style="font-family: Helvetica;
