Thanks, I will try that, but quickly, I often use commas with selection and it works fine, what's the difference between the commas and the colons? On Wed, Jan 30, 2019 at 4:03 PM Elaine Meng <meng@cgl.ucsf.edu> wrote:
Hi Ahmad, The specification is wrong for two reasons: (1) need colon instead of comma, for example #1:.k:.e (2) you would need to either remove the space between the two models or put quotes around the whole thing like "#1:.k:.e #2:.k:.e"
However, more important is that “combine” will include all the atoms in the whole models even if you only specify some chains. It says this in the second paragraph: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/combine.html>
So what you really wanted to do is to delete all the other atoms before you combine the two models, something like
select #1:.k:.e #2:.k:.e delete ~sel combine #1,2
(also make sure you really have models #1 and #2, since the first model is #0 and you might need to use #0 and #1 instead… check in the Model Panel, opened from Favorites menu)
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

I'm trying to combine a few chains from different models. I'm using: combine #1:.k,.e #2:.k,.e. I'm getting the above error, and I'm not sure why my selection isn't working!
