Hi sir, I downloaded chimera 1.13.1 at a website for free. Also, I am able to use the software without any licence needed. I carried out some research work using the software. Presently I am about to submit a paper for publication using your references. In this case, Will it be proper for me to submit a paper for publication using your references. Best wishes Billy.  Sent from Yahoo Mail on Android On Mon, 7 Oct 2019 at 9:21 PM, Tom Goddard<goddard@sonic.net> wrote: Hi Shengyou,   The curvature.py script was attached to the Chimera mailing list message you found. http://www.cgl.ucsf.edu/pipermail/chimera-users/2014-January/009580.html It got renamed with a ".bin" suffix, so after you download you should change the file name to curvature.py.  A similar capability is in ChimeraX, the "measure convexity" command https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/measure.html#convexity Here's an example image using "measure convexity #1" on EMDB 0074.

Thank you very much for your help!
