Hi Elaine, Zheng, Thank you so much for all your input and quick responses. As suggested, I used the python script in chimeraX and it worked perfectly! Best wishes, Kelly

Thanks, Zheng!
By the way, if these values are already assigned as bfactor, another way is to use the python method from the previous post, which might be easier:

After that you would still need to set the atom style of the tunnel model to "sphere" to see the radii.

Hi Kelly,
I tried to visualize the tunnel output from caver recently. The workaround is to manually set the atomRadius for each dummy atom of the caver tunnel output. It will be something like this in the script file:
size #2:1 atomRadius 8.45 size #2:2 atomRadius 8.70 size #2:3 atomRadius 9.03 size #2:4 atomRadius 9.45 size #2:5 atomRadius 9.94 size #2:6 atomRadius 10.49 size #2:7 atomRadius 11.10 size #2:8 atomRadius 11.75 size #2:9 atomRadius 11.96 size #2:10 atomRadius 11.78 size #2:11 atomRadius 11.67 size #2:12 atomRadius 11.64 size #2:13 atomRadius 11.69 size #2:14 atomRadius 11.81
Best, Zheng

I am using ChimeraX to visualise a tunnel found in my membrane protein using caver. I can put together the protein pdb and tunnel pdb perfectly. However, crucial to the figure is how the tunnel has a different radius throughout. In PyMol I can see this, but when I set the tunnel to sphere in chimeraX, it’s continuously the same diameter. I can change the colouring to b-factor and here it acknowledges the atom b factor range of 0.8 - 4-8 but I want to visualise the differences.
Please can someone help me with a command?
BW, Kelly
