[chimera-dev] need your help

Hi Johannes,
	The "write relative" command provides this functionality, but I guess 
we didn't anticipate writing out structures relative to non-molecule 
models, so the command doesn't work when the "relative model" is a 
volume (we will fix this for the next release).  There is a workaround. 
  After you have positioned your structure as desired with respect to 
your volume, open any structure whatsoever into the same model number 
as your volume, then use "write relative".  So, if your volume was in 
model 0 and the structure you want to write is in model 1, you would:

	position the models the way you want
	open 0 any.pdb
	write relative 0 1 transformed.pdb

If you wanted to continue working and get rid of the extra structure 
you had to open, use the Model panel to close it ("close 0" in the 
emulator would close the volume also).
