[Apologies if you see this more than once]

I would like to announce the release of an updated and expanded set of
tools for sequence analysis in Stata:

SADI: Sequence Analysis Distance Measures

The package calculates Optimal Matching distance, and a number of other
inter-sequence distance measures, and has a set of utilities for
handling and summarising sequence data.

Included in the distance measures are Dynamic Hamming, Time-Warp Edit
Distance, and a spell-oriented version of Elzinga's
number-of-matching-sequences method.

It uses plugins for some of the most intensive operations, so it is very
fast, but is restricted to 32- and 64-bit Linux and Windows. If you
would like to compile it for a different architecture, I would be happy
to cooperate. 

To install do

. net from
. net install sadi

It depends on -mm_expand()- from moremata, so also do

. ssc install moremata

For more information, there is an extended discussion of the package,
with worked examples, in
