SpletThe range of allowed values depends on the relevant pull geometry (see pull-coord1-geometry). For periodic geometries awh1-dim1-start greater than awh1-dim1-end is allowed. The interval will then wrap around from +period/2 to -period/2. awh1-dim1-end¶ (0.0) [nm]/[rad] End value defining the sampling interval together with awh1-dim1-start. SpletAbstract. An extensive conformational search in explicit solvent was performed in order to compare the influence of different long-range electrostatic interaction treatments in molecular dynamics. The short peptide endothelin-1 was selected as the subject of molecular dynamics studies that started from both X-ray and NMR obtained structures.

SpletFor the cutoff distances typically used in simulations (ranging between 0.9 and 1.4 nm), and considering the large magnitude and long-range nature of the electrostatic interactions, abrupt truncation of these interactions in a straight-cutoff approach leads to large errors in many simulated properties. 20,25–28 For the LJ interactions, the ...

SpletFor the short cutoff distance, the conformations deviated far away from the initial structure and were significantly distorted.
