minimization error
by Elaine Meng 03 Feb '23

Dear Alaa, Forwarding your question. However, when you get a Chimera error and you think it may be a bug, instead of using e-mail it is usually more helpful to use the Chimera menu: Help... Report a Bug. Also make sure you are using a recent version of Chimera. If you haven't updated in a while, you should try the newest release, then if you still get the error, you could report it.

A question about "Distance Measure"
by squirrel 03 Feb '23

03 Feb '23

Dear Ms/Mr： Thanks for your wonderful tool! I meet a problem recently. Every proteins have N-terminations and C-terminations, and I want to measure the distance between all proteins at each other's N-C, N-N, and C-C terminals by using UCSF Chimera. But there are too many proteins for me to start.I've read Chimera's tutorials and searched my questions online. But I didn't find the answer I needed.Can you please give me some guidance or tips？

Announcement: Release of DOCK 6.10
by Scott Brozell 01 Feb '23

01 Feb '23

We are pleased to announce the release of DOCK 6.10. DOCK is a suite of programs for molecular docking. The source code for DOCK 6.10 is available for download and free for academic users at http://dock.compbio.ucsf.edu/DOCK_6/index.htm This is a release of the new genetic algorithm DOCK_GA: Molecular evolution for ligand design. DOCK_GA evolves molecules through breeding, mutation, fitness pressure, and selection. The method leverages powerful sampling, scoring, and searching routines previously implemented into DOCK 6. For full information on what is new in DOCK 6.10, please visit: http://dock.compbio.ucsf.edu/DOCK_6/new_in_6.10.txt Sincerely, The DOCK Team Please visit us at the DOCK Web site. http://dock.compbio.ucsf.edu

Specifier for the z-axis
by Yang Shi 29 Jan '23

Dear Chimera-Team, I am wondering if there is a specifier for the z-axis of a map. I would like to measure the angles between defined plains and Z-axis. Best wishes, Yang

smooth-MD.py script
by Enrico Martinez 26 Jan '23

26 Jan '23

Dear Chimera Users! I am looking for the smooth-MD.py script that I may use with MD trajectories to smooth their visualization. I've already seen it for Chimera-X but it seems that the older version is disappeared ... Many thanks for any info! Yours sincerely Enrico

Rotation along symmetry axys
by Leonardo Talachia Rosa 25 Jan '23

25 Jan '23

Dear Chimera team, I hope you are well. I am processing a phage dataset which presents D5 pseudossymetry. The C5 axys is aligned to the z axys. I would like to rotate the map 90 degree in the z axys, so that Z axys now separate the molecule in a C2 pseudosymmetry, in order to play with some symmetry relaxation features to refine differences in the two map vortexes. Is there a way in chimera to rotate the map in relation to the xyz axys? The way I see, all rotate commands I know rotate the axys themselves alongside the map. Thank you for your time, Kind wishes, Leonardo -- ************************* Leonardo TALACHIA ROSA, PhD PostDoctoral Researcher Microbiology and Structural Biology Instituto de Química, Universidade de São Paulo - IQ-USP Av.

Error in energy minimizaion - reg
by SELVA BABU SELVAMANI 24 Jan '23

24 Jan '23

Dear Developers, I did phosphorylation of amino acid in protein, then I was about to do energy minimization using Chimera MINIMIZE STRUCTURE module, but it is throwing the error ( I mentioned below ). **************************************************** Running PARMCHK for PP.pdb Using main parameter file parm10.dat modified by heme-iron.frcmod, frcmod.ff14SB, frcmod.ionsjc_tip3p *Chimera/MMTK cannot minimize structure, probably because there is no parameter for ''No parameters for bond Atom 0.TPO_144__0_0_1_145.N (atom type n) - Atom 0.GLN_143__0_0_1_144.peptide.C (atom type C)''* ********************************************** *Please help me to sort out the issue.* I also tried to do phosphorylate using Chimera, even that structure also getting the same error while doing energy minimization. -- *Have a nice day,* Thanks & Regards, *SELVA BABU S* M.Sc Scholar (Bioinformatics) *TNAU, Coimbatore*

how to save molmap by command line
by Guido Leoni 23 Jan '23

23 Jan '23

Dear list I would use in programmatic way chimera to elaborate a molmap of a peptide bound in a receptor. I'm able to load the pdb and elaborate the molmap of the peptide "/home/guido/.local/UCSF-Chimera64-1.16/bin/chimera --nogui load <NAMEFILE> molmap :.P 5;" Now I would save the molmap of the peptide to do a fitmap vs another peptide. I tried save test.mrc but the following msg is prompted to me Volume data sets molmap <namefile>.pdb res 5 were not saved in the session. To have them included in the session they must be saved in separate volume files before the session is saved. DO you have any tips? Thank you Guido

ChiMera: Judith N. Pichel Ford 1999
by Amy Ford 20 Jan '23

20 Jan '23

Hello, I am Amy Ford. My maternal grandmother is Judith N. Pichel Ford (1939-1999). My grandmother was a true fetal ChiMera and her body was studied after her passing in 1999 in the State of New York. I am trying to locate any documents and genetic information that concerns my grandmother so I can understand my health more. I understand that ChiMerism can be passed and filtered through the X Chromosome, I am willing to participate in any future or ongoing studies concerning the nature given my disposition. Please contact me if you have any information of my grandmother, possible trail, or interest in reaching out for a study. Thank you for your time, Amy R. Ford

problem
by Jianan Li-Harbin Medical University 15 Jan '23

15 Jan '23

Dear Chimera developers： I have a problem in using Chimera！ I want to save a ligand-receptor complex file for further analysis，but I can not save a such PDB file！You can see the figure below！ The target was protein, and the atr_1 was the ligand, all files were saved from the dock results of Swissdock online tool (figure 2)! I hope you can help me, thank you very much! Best wish, Jianan Li Jianan Li-Harbin Medical University 364453372(a)qq.com
