• Description:

  Increments the selected elements of the backbone by one. If no elements are selected, selects the first element. Useful for stepping through the protein to check if everything in inside the good regions on the rama map

Code

-- Make a list of all of the selected elements
selectedElements = {}
for i=1, structure.GetCount() do
    if selection.IsSelected(i) then
        selectedElements[#selectedElements + 1] = i
    end
end

-- If nothing is selected, select the first element. Other wise, increment the selected elements by 1
if #selectedElements==0 then
    selection.Select(1)
else
    -- Loop through the list of selected elements, and deselect them
    for i=1, #selectedElements do
        selection.Deselect(selectedElements[i])
    
        -- Do not select next element if current element is last one. Doing this will cause a crash
        if selectedElements[i] ~= structure.GetCount() then
           -- Select each element that is one higher than the ones that were currently selected
            selection.Select(selectedElements[i]+1)
        end
    end
end
