Hi Hector,<br>
<br>
Not sure what "sharply chopped" means without a picture. But we have
seen a problem where the map surface looks like sliced bread. It is
caused by a bug in old Mesa OpenGL (3-d graphics) libraries on Linux,
and is not a Chimera bug. The solution is to install a graphics driver
which will also give you much faster rendering. Or you can disable
Vertex Buffer Objects in the Chimera Debug Graphics Driver tool.<br>

If this is not your problem you can submit a bug report with Chimera
menu entry Help / Report a Bug and attach an image.<br>

<div><br>
</div>
<div>Also regarding contouring ED maps: we have ccp4 maps that are
fine in coot, but as soon as you display them in chimera they are
sharply chopped in one direction, as if there is any problem with a
border. Any suggestion, the effect it's particularly bad for a surface
representation, but it's also obvious when you display it as a mesh.</div>
