Hello, I was looking to calculate the dihedral angle, and ChimeraX was giving me a value that I didn't agree with. I ran the same command with the older Chimera, and it's more in line with what I expected

I was looking at the dihedral angle for N-acetyl in sialic acid. ChimeraX gave me 6.9 degrees while Chimera gave me -179.95 degrees. Is there something wrong that I'm doing? It's from the same pdb file.

Regards,

Alex
