This program looks useful, especially for those of you interested in obtaining microsatellites from 454 data or large datasets (e.g. ESTs from Genbank).
It searches fasta files for microsats, and then uses Primer3 for designing primers. We can already do this using Sputnik and Primer3, but Msatcommander does it all in one program, without the need for editing the format of input/output files.
It looks like the source code and executables for most platforms are available.
