Hi Michael,
if by 'unbiased model' you mean what is recently defined as 'gold
standard' protocol, this is not yet implemented in Auto3DEM, or at
least it can not be performed in a transparent manner. It will be
available in the next release, but it will not be before one
month.
At the moment you can only do it manually, by splitting either the
stack files or the parameter (.dat) files. Then you run the
program twice, on the each set of particles, for the number of
iterations needed to achieve convergence. Finally, you need to
assess the resolution by comparing the two maps, and combine them
to get the final result. The tedious operations are splitting and
combining the data, since no tools are currently provided within
the software package.
If you want to try and need some help, you can contact me
directly.
Thanks,
Giovanni
