[Chimera-users] problem with ccp4 map fitting

Dear Elaine, 



Thank you for your answer. Please accept my apologies for the delayed reply.
 Probably I did a mistake when I saved the session because the map was 
included. I work with Chimera briefly. The first link describes the same or 
similar problem but in my case, the suggested solution depicts the map not 
quite correctly. I understand that Chimera was created for a different 
purpose than crystallography. Unfortunately, the COOT graphics is 
unacceptable for papers and websites. I have used Pymol but a map fitting 
and other options have certain imperfections as well. I work on a 
bioinformatics study based on analysis of tens of map files with the 
described problem. 




In case that you find the problem interesting, I am sending you the files: 
the map of water density and the dinucleotide with its hydration sites. 

 
 
Best regards,

Michaela

"Dear Michaela, 
Sessions do not include the map file, so you would have to attach that in 
addition to the session file. 

However, I can see what is happening from the image. Please see this 
previous post, “visualizing maps from Coot in Chimera”: 
<http://plato.cgl.ucsf.edu/pipermail/chimera-users/2016-July/012514.html> 

The following might also be useful, but I haven’t tried the script to see 
what it does:

I hope this helps,

figure out how to make a correct view (in Coot, the map fits the molecule 
well), please, see the image/session in the attachment. I could not have 
found a guidance in the User's guide. Can you help me please?
