Salas, J. J. Sánchez, M. Fondevila, A. Gómez-Tato, J. Álvarez-Dios, M. Calaza, M. Casares de Cal, D. Ballard, M. V. Lareu, Á. Carracedo and The SNPforID Consortium.

Ancestry Analysis in the 11-M Madrid Bomb Attack Investigation. PLoS One, 4(8): e6583, 2009. C. Phillips, L. Prieto, M. Fondevila, A. Salas, A. Gómez-Tato, J. Álvarez-Dios, A. Alonso, A. Blanco-Verea, M. Brión, M. Montesino, Á. Carracedo, and M. Victoria Lareu.

Straightforward Inference of Ancestry and Admixture Proportions through Ancestry-Informative Insertion Deletion Multiplexing. PLoS ONE 7(1): e29684. doi:10.1371/journal.pone.0029684. Pereira R, Phillips C, Pinto N, Santos C, Santos SEBd, et al.

Green links mean fixed training sets. On the other hand, red links mean custom training sets. Available tasks are:

Classification and predicted admixture components as Europ.-Afr.-E. Asian (34 SNPs)new

Classification and predicted admixture components as Europe-East Asia.-Africa-America-Oceania (34 or 46 SNPs)new

Classification with a custom Excel file of populations

Classification with a custom Excel file of frequencies

Classification and predicted admixture components with a custom Excel file of populations (.xlsx format)new

Classification and predicted admixture components with a custom Excel file of frequencies (.xlsx format)new

Thorough analysis of population data of a custom Excel file

Profile generator for all of the above cases

Plot some or all the populations of a custom Excel file

We also give credit to our students Lorena Rodríguez and Ismael Rodríguez for their respective contributions to the Excel file read routine and the density Java applet.
