From FFMD simulations, we extract the H TMA -H W structural correlations in real (R) space and observe the impact of ECC thereon. Since Q-space and R-space are different representations of the same solution structure, the effects are reflected differently in each of them. In real space, this manifests as a subtle change in the radial distribution function (RDF) over a broad range of R values. In contrast, in Q-space, the same structural difference appears as a significant change at low Q values. Experimentally, it is challenging to measure all the low Q data due to the limitations in detector positioning, specifically their proximity to the direct beam passing through the sample.
