• Description:

  Freeze all backbone segments that are not loops (i.e. Helixes, Sheets). Useful when you just idealized the SS, and do not want a wiggle or shake to mess it up.

Code

preSelected = {}



for i=1, structure.GetCount() do
    if selection.IsSelected(i) then
        preSelected[#preSelected+1] = i
        selection.Deselect(i)
    end
    if (structure.IsLocked(i) == false) then
        
        if (structure.GetSecondaryStructure(i) ~= "L") then
            selection.Select(i)
        end
    end
end


freeze.FreezeSelected(true, false)
selection.DeselectAll()
for i=1, #preSelected do
    selection.Select(preSelected[i])
end
