I'm going to try to start writing down some of our discussions during our Thursday Chimera meetings. My first stab at the current issues may be found at https://www.cgl.ucsf.edu:8000/intranet/chimeradevelopment/2002-04-18.html There is also a link from the intranet page to the list of available pages (currently one :-). If I've left off an issue, please let me know and I will revise. Conrad
