[Chimera-users] fit into map global

[Elaine Meng]

Hi Dieter,
The global option is in the "fitmap" command only (not the dialog).  See "fitmap" with global search options:

<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html#global>

There is also a video tutorial linked to that section.
I hope this helps,
Elaine

P.S. ChimeraX has the same fitting as Chimera, if you ever want to switch.  The command syntax is (slightly) different but methodology the same:

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?
