Acc. twist = accumulated twist values (deg.) above and below the reference base-pair. x = If the reference plane is located between two basepairs, one base-pair is duplicated for the calculation (two x's). If the reference plane coincides with one base-pair no duplication is necessary (one x) index bp-step frac.tilt frac.roll bp-step angle orient angle global tilt global roll Acc.twist refbp 1 T-A 0.018 0.982 0.000 88.947 0.000 0.000 322.790 2 G-C 0.285 0.715 2.883 73.428 1.540 2.437 322.790 3 C-G 0.648 0.352 3.172 49.627 2.553 1.883 287.700 4 A-T 0.337 0.663 3.131 70.290 1.819 2.549 249.700 5 A-T 0.717 0.283 2.939 44.181 2.489 1.563 214.620 6 T-A 0.490 0.510 3.253 60.682 2.276 2.324 178.660 7 T-A 0.282 0.718 2.890 73.598 1.536 2.448 142.980 8 G-C 0.643 0.357 3.176 49.980 2.547 1.898 107.020 9 C-G 0.353 0.647 3.169 69.346 1.882 2.550 71.930 10 G-C 0.718 0.282 2.955 44.139 2.503 1.570 33.940 11 T-A 0.502 0.498 3.246 59.856 2.300 2.290 0.000 x 12 G-C 0.285 0.715 2.936 73.433 1.568 2.482 -35.090 13 C-G 0.639 0.361 3.170 50.300 2.534 1.905 -73.090 14 A-T 0.352 0.648 3.155 69.415 1.871 2.540 -108.180 15 A-T 0.712 0.288 2.927 44.638 2.469 1.572 -144.140 16 T-A 0.503 0.497 3.239 59.780 2.298 2.282 -179.810 17 T-A 0.286 0.714 2.921 73.391 1.562 2.468 -215.770 18 G-C 0.649 0.351 3.157 49.512 2.544 1.869 -250.860 19 C-G 0.349 0.651 3.146 69.547 1.860 2.537 -288.860 20 G-C 0.711 0.289 2.889 44.705 2.435 1.554 -322.790 sum. 9.479 10.521 58.352 1218.795 40.583 40.723 313.540 ave. 0.474 0.526 2.918 60.940 2.029 2.036 15.677 S.D. 0.174 0.174 0.139 11.731 0.400 0.388 201.938 The global bend-angle = 57.492 **************************************************************************************************************
