Hello Chimera community I am trying to run the “rna model sequence #0” code but it is returning the following error: IndexError: list index out of range File “…path/RNALayout/rna_layout.py”, line 393, in place_residues rprev = rlist[0] See reply log for Python traceback. Anything elementary that I am missing? My fasta file is very simple and it is stored in the Documents folder.

Re: [Chimera-users] ResProp Python code
by Elaine Meng 05 Apr '21

05 Apr '21

Dear Chittari Jaya Shree, I can't answer about python, but maybe you didn't know about the related feature that you can simply assign names to whatever you want. There is no need to use the ResProp tool if this is all going to be in a script anyway. For example, command: alias neutral :ile,val,leu,phe,cys,met,ala,gly,thr,ser,trp,tyr,pro,gln,asn ... will then let you use "neutral" in other commands, e.g. select neutral "alias" command <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/alias.html> I hope this helps, Elaine ----- Elaine C.

HI Elaine, I want to know the rotation and translation components along x,y and z separately from the rotation matrix obtained from chimera reply log upon fitting a model into a map. Will it be possible to know? Matrix rotation and translation 1.00000000 -0.00000000 -0.00000000 1.83458738 -0.00000000 1.00000000 -0.00000000 1.15016978 -0.00000000 -0.00000000 1.00000000 -0.53835221 Axis 0.00000000 0.00000000 1.00000000 Axis point 0.00000000 0.00000000 0.00000000 Rotation angle (degrees) 0.00000000 Shift along axis -0.53835221 thanks, Ashok

count the selected residues in linux terminal
by Jayashree Chittari 01 Apr '21

01 Apr '21

Respected sir/ma'am Greetings for the day! I want to use chimera commands in shell scripting or python. So, my problem is how to count the residues using Chimera? in gui we know that there is a magnifying icon at the lower right portion of the window, but while running in linux terminal I'm unable to generate the same results. Here is the attached ss of inspect selection, so if I want to print this in linux terminal what steps should I follow to get to this result? I'm trying my best to search in the tutorials but unable to create a command related to inspect selection. Kindly help me in this issue, it would be very grateful if you suggest the code. thank you, Regards Chittari Jaya Shree

Questions about probabilities in the Dunbrak library
by Moradkhan, Tiglath A 01 Apr '21

01 Apr '21

Hi I'm trying to understand the meaning of probabilities in the Dunbrak library. From what I've found, this parameter is a measure of how probable a particular rotamer is to be found within a given conformation. Is this what this is? Thanks Tiglath

in *.gro file, chimera takes CL atom as C (in compound) and gives it wrong color
by Lei Qian 31 Mar '21

31 Mar '21

Dear users, Could I ask a question on chimera? Thanks! I tried to open a gro file (small compound) using chimera. Like below: ... ... 1 LIG CL 18 x.xxx x.xxx x.xxx 1 LIG CL1 19 x.xxx x.xxx x.xxx ... ... Although chimera shows the CL name "CL" when the cursor is above the atom, but the CL atom color is incorrect: the same as Carbon. I tried to change the "CL" to "BR", and the chimera shows the correct color: dark red. It seems weird to me. Could you please give me any suggestions? Thanks! Best, Lei

No MMTK name for atom "HD2" in standard residue ASN
by Sina Analoui 31 Mar '21

31 Mar '21

Hi All, I am currently attempting to minimize a large molecule (ACE2 alongside the RBM of a spike protein). I Dock Prep both chains (A chain is ACE2) and then go on to attempt to minimize them. However, I keep returning this error "No MMTK name for atom "HD2" in standard residue ASN" I have attempted to remedy this by rewriting parts of the PDB file and importing it back in and have had no success. Is there any way to either remove NAG that is associated with these residues or change this hydrogen to something feasible? This seems to be an issue for only the ASNs on the A chain and not elsewhere on the molecule Thank you in advance for your help
