• X-ray_pattern.zip: Here are the two X-ray diffraction patterns for the 20wt% PBDT solution and the H2O background. The matlab script to generate the subtracted image is also included.
• MD_DATA.zip: 1. The coordinates of the snapshots show the two PBDT polyanions at 0 ns, 10 ns, 20 ns, 30 ns, and 120 ns in the MD simulation. The gro file format is the standard coordinate file used in the Gromacs package.
