[Chimera-users] fit into map global

[Dieter Blaas]

Hi Elaine,

    thank you! Can you please give me an example for the command. To 
simulate a map from the pdb model at 10 A I tried "fitmap #1 #0 r 10" or 
"fitmap r 10 #1 #0" or "fitmap r=10 #0 #1" and many other combinations 
but I always get an error message! How are the parameters to be set?

Thanks again, best Dieter

I usually succeed after a very long process of manually positioning the model approximately and then running 'fit into map' that arranges it in the best way.  I filtered the map to low resolution and used the option to generate a density map of the pdb file which makes it easier but it is still complicated. However, I believe that there is a routine to globally fit that does not require the very cumbersome first manual fitting. Can anybody please give me a hint?
