This change will only affect people who run large-scale simulations (more than about 10000 cylinders or so) using gamma-distributed cylinders. The change is to the algorithm used to generate the radii of the cylinders and replaces the previous method with a new one with improved performance and convergence. Samples from the new method converge much faster on the underlying gamma distribution and are faster to generate, and unlike the previous algorithm has uniform performance across all parameter values.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If you don’t run simulations with gamma-distributed substrates this won’t affect you at all.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If you do run simulations with gamma-distributed substrates, the new method will improve the accuracy and precision of the synthetic signals. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If you’re running simulations with gamma-distributed substrates and more than about 10000 cylinders, the new method will be particularly helpful.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Hope this is useful,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Matt.<o:p></o:p></p></div></body></html>
