Hi, I am trying to make metal coordination bond as a dotted line and also I need to make electron clouds around the atoms as in the picture below (Please provide me short guidelines on how to make nice cartoon). Please help me sort this two issues. Looking forward to hearing from you, Many thanks, Thiru [image: image.png] -- Thirumurugan Prakasam, Research Scientist, New York University Abu Dhabi, Experimental Research Building Building C1, Saadiyat Island Abu Dhabi, UAE Phone no: +971-561976358

morphing
by Francesco Malatesta 30 Mar '20

30 Mar '20

Hello I am trying, for teaching purposes, to morph deoxy hemoglobin 1HBA and oxy hemoglobin 1BBB to show the O2-linked quaternary change. I get an obviously wrong morph, attached. Chimera is probably pairing different subunits? Do you think this morph can be done?

Keyboard shortcuts for DockView?
by James Wagstaff 30 Mar '20

30 Mar '20

Hi all I am using the DockView extensions to inspect outputs of a virtual screen, and would like to use a keyboard shortcut to (re)assign the state of the currently selected compound. I am not familiar with the inner workings of Chimera so cannot easily see how to do this myself - I am hoping someone else has implemented this! Best James -- James Wagstaff +447910113349

NMWiz plugin
by George Tzotzos 27 Mar '20

27 Mar '20

Hi everybody, I downloaded the NMWiz Chimera plugin from github: https://github.com/prody/NMWiz-chimera <https://github.com/prody/NMWiz-chimera> From Chimera/Tools/Additional Tools/Add third-party plugin-location, I used the add button to point to the downloaded plugin folder. This doesn’t seem to work. Is there another way to add this plugin? Is it compatible with Chimera 1.14 Thank you in advance for any suggestions

Hi Elaine, thank you a lot for your fast response! Your suggestion helped and my problem is solved :-) Best regards Benedikt -----Ursprüngliche Nachricht----- Von: Elaine Meng <meng(a)cgl.ucsf.edu> Gesendet: Dienstag, 24. März 2020 18:27 An: Benedikt Moissl <benedikt.moissl(a)biologie.uni-regensburg.de> Cc: chimera-users(a)cgl.ucsf.edu BB <chimera-users(a)cgl.ucsf.edu> Betreff: [EXT] Re: [Chimera-users] Problem with electrostatic surface Hi Benedikt, You still need to show the surface of your molecule, e.g. with command "surface #0 & protein" (or "surface #1 & protein" since they are the same atomic coordinates). After you do that, it will be listed in the menu of choices of what surface to color in the Surface Color dialog. I hope this helps, Elaine ----- Elaine C.

I ran the PDB2PQR tool as described in the user guide and obtained a PDB2PQR file. With that, I ran the APBS tool and obtained a .dx file. As described, the Surface Color panel opens automatically, but here I am unable to choose my structure file for "color surface" (s. attachment 1). I can only choose the .dx file, which does not work. All three models obtained during this process are opened in the model panel though (s. attachment 2). > > Do you have any idea on how to fix this? > > Thank you very much in advance and keep up the great work! > Benedikt Moissl

Re: [Chimera-users] cobalt in Chimera

That message says that ANTECHAMBER charge calculation failed on the non-Co part of residue B12, which means all the rest of the atoms besides Co, which is handled separately. That residue is large and complex and has a phosphate, all factors that are more likely to cause a failure of the AM1-BCC charge calculation method. You may have to use the simpler charge calculation method "Gasteiger" as specified in the Add Charge dialog. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/addcharge/addchar…> (For next time, to ensure you get an answer please send Chimera questions to chimera-users(a)cgl.ucsf.edu, CC-d here, rather than my individual address.)

Problem with electrostatic surface
by Benedikt Moissl 24 Mar '20

Dear Chimera team, I am trying to display color the surface of my molecule according with Poisson-Boltzmann electrostatics using Chimera 1.14. I ran the PDB2PQR tool as described in the user guide and obtained a PDB2PQR file. With that, I ran the APBS tool and obtained a .dx file. As described, the Surface Color panel opens automatically, but here I am unable to choose my structure file for "color surface" (s. attachment 1). I can only choose the .dx file, which does not work. All three models obtained during this process are opened in the model panel though (s. attachment 2). Do you have any idea on how to fix this? Thank you very much in advance and keep up the great work!
