This page suggests there should be a command called 'magick-script', which I cannot find in the installation folder. Is this not included in the 7 install?

Btw, on the plus side, with the version 7 64 bit build I can generate much larger event counts. I've got a test image of 100k events on a 20000x14000 image. Using 3.2GB of memory. It appears to be using multiple cores as well. The 64 bit aspect probably made the biggest difference, but still this is promising.

Is there an alternative to auto_level that will allow me to set the min/max range with which to level based on? In some cases there are events that can accumulate high enough to completely wash out other events, so I'd like to clamp it in these cases.

See the docs: http://www.imagemagick.org/script/comma ... auto-level

"-auto-level" is just an automated "-level". Instead you can do "-level 0,200%" (what was black stays black; what was 200% or above of quantum becomes white) or whatever gives you the range you want.
