Change default colour cycle for EM maps
by James Hooker 06 Nov '23

06 Nov '23

Hello all, I am looking for a way to change the qualitative colour cycle in ChimeraX from the default (grey, yellow, blue, purple, pink, …). I have flicked through the online documentation, but have not yet found a solution. Many people must have desired to do this at some point, right? Any advice is welcome! Best, James

commandline to hide a map region or set a transparency in chimeraX
by Rayees Mattoo 06 Nov '23

06 Nov '23

Hi, I was wondering if there is a command line in chimeraX to hide a region of the map. To be more specific if I have to hide map around a model #1 chain A, how could I do that? Also, using the same case how do I set a transparency of 50% for the map around the chainA model #1? Actually, I want to make a movie of the vseries where I need to hide/delete/transparent some portion of the map to show the internal details of the map while playing the vseries. Any suggestions are welcome. Best

problem with color by conservation option
by elzbieta.wator＠doctoral.uj.edu.pl 06 Nov '23

06 Nov '23

Hi, I am trying to color my protein structure by conservation. I prepared alignement file i fasta format and when I upload it to the ChimeraX and use command: color byattribute seq_conservation palette cyanmaroon not the whole structure of my proteins get coloured. Namely despite no mismatch in the PDB file and sequence which is first in aln file there are several residues which stays in the previously selected colour. I've already made sure that the sequence is correct and I have no further ideas how to solve this problems. I will be very grateful for your tips. Best, Ela Wator

Select truncated residues in PDB
by Vorländer,Matthias Kopano 05 Nov '23

Dear ChimeraX team, Is it possible to select all residues in a model that have been truncated to backbones rather build as a complete sidechain? Many thanks, Matthias

mseries oscillate/loop ?
by vincent Chaptal 04 Nov '23

04 Nov '23

Hi again, it is possible to use vseries play #1 loop true, but the same command with mseries doesn't work. Same with oscillate or similar commands. I've also tried mseries #1.1-20-1 or mseries #1.20-1 but these 2 commands don't work. Is there a way to make the movement go back to the origin? Thank you Vincent -- Vincent Chaptal, PhD Director of GdR APPICOM Drug Resistance and Membrane Proteins Lab MMSB -UMR5086 7 passage du Vercors 69007 LYON FRANCE +33 4 37 65 29 01 http://www.appicom.cnrs.fr http://mmsb.cnrs.fr/en/

ISOLDE and heparin
by Xuewu Zhang 04 Nov '23

Dear Tristan, Can ISOLDE handle heparin molecules now? I tried to simulate a heparin chain, it says one residue is not properly parametrized. I am using ISOLDE in Chimerax 1.6. Thanks, Xuewu

fly command
by Sean Connell 03 Nov '23

03 Nov '23

Hello, I have a question about the fly command. I am trying to iterate over a series of saved views (p1-p6) using the fly command. The views are close-up views of residues because I am trying to make a movie similar to that made with resfit. The issue is that the cutting plans don't seem to update as it moves from view to view. Do you have a hint that could let me know what I am doing wrong? Thanks for any tips you have
