Hi Tom, Wow.. that will be awesome!! I can't wait to use this new operation. The operation in Chimera is so cool, we love it.

It will be in tonight's daily build. So to mask the dust on map #0 you could use sop hideDust #0 size 25 sop invertShown #0 mask #0 #0 invert true Would be nice to make this easier -- maybe in our next generation Chimera.

You could set the map grid points to zero inside the dust blobs with the mask command. But first you need to be able to show only the dust and there is no command to do that. I've attached a Python script that does that. You select the map surface (ctrl-click) that you have done hide dust on, then open the surfinvert.py script to show only the dust. Then use the mask command mask #0 sel invert true to mask the density map (#0) to the selected surface (dust blobs only shown) and invert, since you want to keep everything outside the dust blobs, not everything inside the dust blobs. I tried it, works. But if you lower the threshold on the new map then of course you see more dust. Tom <surfinvert.py> The surfinvert.py script is also on the Chimera Python scripts page http://plato.cgl.ucsf.edu/trac/chimera/wiki/Scripts On Dec 8, 2015, at 5:05 PM, Gang (Gary) Ren wrote: Hi Tom, I like the density map after hide density map, is there any way to save the density map after dust hide? Every time I save the density map, it saved the original map instead of density map after hidden dust. Thanks a lot Gary
