[Chimera-users] Helix axis and correction

[Gulsevin, Alican]

Hello everyone,

I have a question about the "helical correction" option for calculating helix axes. I've been trying to find the exact calculation Chimera uses to correct the helix axis, but I couldn't find anything specific in the archives and I also couldn't figure it from the source code. Where can I find a detailed description of how the helix axes and the corresponding corrections are calculated?

Thanks for your help,
