SATé and PASTA
Simultaneous Alignment and Tree Estimation (SATé)
is a software package for constructing phylogenies and
alignments from sequence data.
It is particularly useful for large datasets (hundreds to thousands
of sequences), where it has been shown to produce more accurate
alignments and trees than previous methods.
We have just developed PASTA, which is an improvement to SATé - it is faster and more accurate, and
can analyze larger datasets (up to 200,000 sequences). We suggest you
use PASTA instead of SATé. Contact us if you need assistance.
The algorithmic designs in
SATé and PASTA are under active research development at UTCS by the Warnow Lab
(especially with PhD student
Siavash Mirarab); the publicly distributed
code for SATé is a collaboration with the University of Kansas, under
the direction of

contains datasets and software corresponding to the
original SATé submission. (The new version,
available through the Kansas website, is both faster and has better accuracy,
and we recommend using it instead.)

We are currently developing SATé for amino-acid
analyses, for very large datasets (with upwards of
10,000 taxa), and for use with metagenomic
data (and next generation sequence data
