Rapid Access - a different question/request
by Boaz Shaanan 08 Aug '12

08 Aug '12

Hi Eric, I actually find the Rapid Access very convenient, however I wonder: is the list limited to the n most recent sessions/pdb ? I actually am missing the option of paging further down the list to jobs that are not in the list but which are quite recent. Is there already an option to do this? The browse button does other things (at list in my hands).

Hello, I am trying to script distance measurements (distance monitor) between the Calpha of a residue and a few Hydrogens. I have pretty much everything working except that I am not able to figure out how to change the attributes (color, line style etc..) of the distances (pseudo-bonds). I know it can be changed using the GUI but I would rather script it. Any suggestions?

Hi, I'm trying to get used to the new Rapid Access interface of chimera. But how do you remove the list (or items on the list) on the right side of the interface? Thanks.

SASA vs. MSA
by Nikolay Igorovich Rodionov 05 Aug '12

05 Aug '12

Hi all, I was wondering if you could help me conceptualize what is going on in this situation. I ran both solvent accessible surface area and solvent excluded (molecular) surface area calculations. When I compared the output for both of these calculations I found that, overall, atoms that contribute to the SASA are buried 1-3 angstroms deeper in the protein than those that contribute to the MSA. I don't really understand how this could be unless the deeper buried SASA atoms have a much larger van der waals radii than MSA atoms (I get that some atoms contribute to both). Thanks!

trajectory rmsd
by George Tzotzos 03 Aug '12

03 Aug '12

I'm writing to find out if it is possible to determine the rmsd of specific residues, say 20-120 (backbone atoms only) from a trajectory against the corresponding residues of an X-ray structures. I used the Movie tool to load the trajectory having loaded prior to it the reference structure. I couldn't find a way to compute what I described above. Your help as always is much appreciated Best regards George

Inifinite lattice minimisation
by Kyle Morris 03 Aug '12

03 Aug '12

Dear all, I am trying to do minimisations on a crystal system. I wonder if when chimera knows the unit cell will it minimise as an infinite lattice or do the copies need to be explicitly created before minimisation proceeds? Really appreciate any help/insight. Best wishes, Kyle

combining mrc maps
by Daniel Murin 02 Aug '12

02 Aug '12

Hi, I was wondering if it is possible to combine two mrc volumes into a single volume and save that as a new mrc file? I haven't really been able to find anything and I suspect that this may not be possible with Chimera.

double bonds visualization ?
by Marek Maly 02 Aug '12

02 Aug '12

Hello, I am just curious if it is possible to visualize double bonds as double bonds now similarly like in case of rings one can visualize them nicely (aromatic ring/disc).
