[Chimera-users] Resolution

Hello,
That information would come from the same source as the data, and it may just be easier to look at that source.  In other words, you could go to the RCSB PDB website to check information on a PDB structure, or the EMDB website to check information on a density map from the EMDB.  For links to those websites, see here:
<http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/fetch.html>

Chimera does not calculate resolution. If the source does not provide that information (for example, another scientist gave you a density map in progress), there isn't a way to guess it in Chimera.

However:
In Chimera, you can look up the resolution for a PDB structure if it was in the header of the PDB file.   You would have to open the Model Panel (in menu under Favorites), choose that structure on the left, and then click "attributes..." on the right.  Then, in the resulting attributes dialog, click the "PDB Headers..." button at the bottom to see the header information.  Personally, I find it difficult to find "RESOLUTION" in all this information, so I usually just open the original PDB file in a text editor program (not in Chimera) and search for "RESOLUTION" or look at the RCSB PDB website, as mentioned above.

I hope this helps,
Elaine
