Error on installation on a student's computer
by Kenward Vaughan 11 Jan '22

Hello all, As usual I have my students installing Chimera as part of their continuing adventure in organic chemistry, but have one of them reporting an error on attempted startup after installation. So far I have little information (we haven't started classes yet--next week--but she has sent the error message obtained. It is apparently on Windows. I suggested that she try starting from the command line to do the debug run, but this is from a distance at this time and I don't know how savvy she is with such stuff. Is there enough information in just the number noted by this message for someone to know what might be happening with her setup? Many thanks, and cheers!

Hi, Having superimposed 4 structures using MatchMaker, is there a way to view the aligned structures in a window grid? Moving them manually after superimposition is not optimal. Thanks in advance for any suggestions and best wishes for 2022

Introduce a-helices into protein structure ab initio
by Chara Spanou 06 Jan '22

06 Jan '22

Hello chimera-users, I would like to introduce a-helices into my protein structure ab initio. Is it possible to do this with chimera? Another option that I have is to take a-helical pieces of sequence from a different model and introduce these into the desired model. Would that be more feasible? There is a chance I also need to introduce loops and turns ab initio to best localize the introduced a-helices within my protein structure. Can you please indicate how can a chimera user build all this ab initio? Thank you in advance for your time and help, Chara SpanouPhD studentUniversity of Cologne

Question: PDB file creation
by Kenji MATSUI 05 Jan '22

05 Jan '22

Dear Chimera company Thank you for allowing me to use your software. I am Japanese, so I hope you will understand that there are some inappropriate expressions. I would like to ask you one question. I would like to know how to overlay the docked protein (osh4)-ligand (cholesterol) complex (the gray one in the figure) and the complex on the PDB. [image: image.png] Aim I would like to know how well the docked data matches the data in the PDB. Methods I have tried I did it based on the following link from Chimera. https://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/matchalign/matcha… Thank you for your cooperation. --------------------------------------------------------------------------- 松井健治東京農工大学大学院工学府産業技術専攻修士〒184-8588 東京都小金井市中町2-24-16 Mail: s214903z(a)st.go.tuat.ac.jp Kenji Matsui Graduate School of Tokyo University of Agriculture and Technology 2-24-16, Nakamachi, Koganei-shi, Tokyo 184-8588, Japan Mail: s214903z(a)st.go.tuat.ac.jp

Opening .py files
by Henry Shook 04 Jan '22

04 Jan '22

Chimera User Support, I'm working on dockprepping the sars-2 main protease and whenever I try and save it as a .py file, I can't open it from sources other than the saved session I wrote. Whenever I try and open it from a dropbox or my finder, I get the message: Error while processing /Users/8642165/Desktop/Research/DC AP Research /[7l0d]DOCKPREPPEDFINAL.py: File "[7l0d]DOCKPREPPEDFINAL.py", line 1 @<TRIPOS>MOLECULE ^ SyntaxError: invalid syntax File "/Applications/Chimera.app/Contents/Resources/share/chimera/__init__.py", line 1325, in _openPython loadFunc(sandboxName, fileName, f) See reply log for Python traceback. Is there any way that I can fix this problem? Thanks, Henry Shook
