Hi Zhiheng, Here is a script to write out the maps in memory using Chimera 1.2199. You open this script with menu entry File / Open... from the main Chimera window. It will write the files to /tmp. Of course be sure to check those files before closing Chimera. Tom Zhiheng Yu wrote:

Hi Tom,

I got the following information:

Beta Version 1 build 2199 2006/01/24 Platform: linux 2. Windowing system:x11.

Apparently, it is an older version.

Thank you very much for your generous help. I really appreciate it.

Hi Zhiheng,

You must be using an older version of Chimera. Old versions read the original file even if the map was in memory when writing out the data. Maybe I can give you a script that will write the maps out from memory if you tell me what version of Chimera you are running (menu entry Help / About UCSF Chimera).
