Select ΔLL = 9 bp fibers with alternating sequence (x,y,x,y...) linker lengths of a) 18/27 bp, b) 36/45 bp, and c) 63/72 bp. Shorter linkers encourage long-range contacts, and large linker lengths diminish local contacts as well as long-range contacts, similar to the randomly distributed case. Fibers with 36/45 bp linker lengths, however, show more compaction and a hairpin fold, absent in the random case. See supporting information for similar plots of all other fibers tested.
