Hi there, I have a color spill problem when drawing a few figures of a hexamer. The coordinates of 6 protomers were saved into a PDB file. I wanted to color chain A red and the rest gray, so I selected chain A and colored it with red. The red color strangely spilled to an N-terminal segment of the next chain. I think there is some problem with the format of my PDB file, but don't know exactly what is wrong. Here's the end of A and begin of B where spill happend: ATOM 2657 C ASP A 418 74.297 91.204 65.520 1.00 0.00 P1 C ATOM 2658 OT1 ASP A 418 73.965 91.654 66.693 0.00 0.00 P1 O ATOM 2659 OT2 ASP A 418 73.731 91.612 64.449 0.00 0.00 P1 O ATOM 2660 N ASP A 418 74.565 88.894 65.731 1.00 0.00 P1 N ATOM 2661 CA ASP A 418 75.338 90.111 65.514 1.00 0.00 P1 C ATOM 2662 CB ASP A 418 76.099 90.113 64.183 1.00 0.00 P1 C ATOM 2663 CG ASP A 418 77.091 91.332 64.042 1.00 0.00 P1 C ATOM 2664 OD1 ASP A 418 76.837 92.210 63.175 1.00 0.00 P1 O ATOM 2665 OD2 ASP A 418 78.018 91.382 64.875 1.00 0.00 P1 O ATOM 2666 N LEU B 87 68.825 113.707 134.628 1.00 0.00 P2 N ATOM 2667 CA LEU B 87 68.215 113.786 133.272 1.00 0.00 P2 C ATOM 2668 CB LEU B 87 67.055 114.822 133.239 1.00 0.00 P2 C ATOM 2669 CG LEU B 87 66.068 114.738 134.402 1.00 0.00 P2 C ATOM 2670 CD1 LEU B 87 65.132 115.985 134.379 1.00 0.00 P2 C ATOM 2671 CD2 LEU B 87 65.430 113.355 134.203 1.00 0.00 P2 C ATOM 2672 C LEU B 87 69.159 114.128 132.171 1.00 0.00 P2 C ATOM 2673 O LEU B 87 69.384 113.413 131.199 1.00 0.00 P2 O Any suggestion?
