Here is the link to the user manual; there is an image of the matrix definition file on page 9.

Martin Kulldorff is on at least one of the publications with the Japanese group that designed FlexScan, which is a sign in its favor. He's never incorporated it into SatScan, however.

FlexScan seems to be distributed as a closed-source Windows-binary only piece of software:

which raises lots of "avoid at all costs" red flags for me.

The methodology is published and could be re-implemented as an R package by a smart enough programmer... Are we too late for a Google SoC project?
