Hi Wen,

It looks to me like the jags.model() command doesn't properly  
interpret the "~wec017" part of the file location correctly.  If you  
use the explicit name:

   /home/wec017/rohde_levy_kehler_analysis.bug

it should work properly.

Note however that I noticed that the .bug file had upper-case V's and  
A's where they should have been lower-case. I just fixed this in the  
file in the /local/contrib/lign274/modeling_code directory tree.

Roger
