Re: [Sgems-users] Re-simulation threshold & Iteration

[Alexandre B. <abo...@st...>]

Hi Pedro,

 Recall that snesim extracts a data event and try to find the exact
replicate in the search tree.  When there is no such replicate, the farthest
away pixel is dropped until that data event is found.  As the simulation
progress, the program records for each location how many pixels have been
dropped. The idea is to resimulate the pixels where a lot of data have been
dropped.    Snesim will then use another random path to re-simulate times
these pixels n times.  In some instances it helps at improving continuity.

Re-simulation threshold controls which locations will be re-simuated (it is
in % dropped) and 'Re-simulation Iteration' controls howmnay times they will
be simulated.

Best,
Alex
