Hi all, thanks so much for all the answers!!! I asked for a software that could identify individuals with the same microsatellite profile among several loci. There's some of the sugestions that I received: Excel adds: GenAlEx GENECAP (Wilberg, M.J. & Dreher, B.P., GENECAP: a program for analysis of multilocus genotype data for non-invasive sampling and capture-recapture population estimation. Molecular Ecology Notes 4, 783-785 (2004).) Others: GenoDive http://www.bentleydrummer.nl/software/software/GenoDive.html Geneclone, but this one not allows non-available data Cervus http://www.fieldgenetics.com/pages/home.jsp - just click on "Identity checker" GenClone 2.0 http://www.ccmar.ualg.pt/maree/software.php?soft=genclon Microsatellite toolkit http://animalgenomics.ucd.ie/sdepark/ms-toolkit/ R (AutocoR) New Hybrids MSA http://i122server.vu-wien.ac.at/MSA/MSA_download.html Dropout http://www.fs.fed.us/rm/wildlife/genetics/software Network sibelletorres@gmail.com
