<div dir="ltr">Hi Tom,<div><br></div><div>Thanks very much! After changing the first line to 2.1, it tells me "Did not find "define Lattice" mesh size line". So I guess there are some "fundamental" changes. </div><div><br></div><div>The only .am file I have now is quite large in terms of debugging (64MB). I found two examples by googling "AmiraMesh BINARY-LITTLE-ENDIAN "3.0"". They give me "Did not find "Lattice { float ... }" line" after fooling ChimeraX. In case I get a smaller one or I got to know the way to crop only a small section and export a smaller one. I will let you know. I will also go through "Report a Bug".</div><div><br></div><div><a href="https://edmond.mpdl.mpg.de/imeji/file/60/17/dc/32-bf46-4e34-b9ba-f02d2fe070b4/0/original/ae8b3e16a7a0f881f66b804ceac50b97.am?filename=190522a_STACK.labels.am">https://edmond.mpdl.mpg.de/imeji/file/60/17/dc/32-bf46-4e34-b9ba-f02d2fe070b4/0/original/ae8b3e16a7a0f881f66b804ceac50b97.am?filename=190522a_STACK.labels.am</a></div><div><a href="https://edmond.mpdl.mpg.de/imeji/exportServlet?format=file&id=http://edmond.mpdl.mpg.de/imeji/item/IoNX5MO0lyzezIwX">https://edmond.mpdl.mpg.de/imeji/exportServlet?format=file&id=http://edmond.mpdl.mpg.de/imeji/item/IoNX5MO0lyzezIwX</a><br></div><div><br></div><div>Thanks,</div><div>Roden</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Oct 25, 2021 at 8:37 PM Tom Goddard <<a href="mailto:goddard@sonic.net">goddard@sonic.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;">Hi Roden,<div><br></div><div>The ChimeraX reader is for AmiraMesh format 2.1 and you are trying to read a version 3.0 file.
