The message suggests your computer can't do the shadows. It might help to update your graphics driver, but I don't know for certain. However, other "set" options should work, for example:
set bgColor white
As mentioned in the "rna duplex" description, the path file is created using the command "rna path":
Also, as mentioned in an earlier message you have to get a daily build (version 1.9), also available from our download page, to use the "helical DNA/RNA" option in Build Structure.
It is recommended to send chimera questions to chimera-users at cgl.ucsf.edu instead of to me directly.
