Binary AIM classification of individuals

You are entering our portal on SNP-Indel classification, hosting the Snipper App suite version 2.0. It is the companion site to several papers.

  • Snipper 2.0 uses the .xlsx Excel format. Users can still access the legacy .xls classifier
  • It lets you turn on/off the Hardy-Weinberg equilibrium assumption, classify multiple profiles and shows you a summary of
  • It sports a new utility to fine-tune your training/testing
  • Multinomial logistic regression is now available to classify single profiles or analyse training
  • A genetic distance classifier providing more reliable admixture proportions is now
  • Principal component analysis (PCA) to classify multiple profiles is now available. PCA and 2D graph points show names of individuals when moused
  • Snipper 2.0 is now a searchable web
  • A new input file generator wizard will help you create your input files, whether you need a training-set-only file, or a training-and-testing-set
  • New skin-, hair- and eye-colour classifiers are now

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

Classification as Europe-East Asia-Africa-America-Oceania (34 SNPs, 46 Indels, or both sets)

Classification as individual having black-intermediate-white skin

Classification as individual having fair-dark or red-blond-brown-black hair

Classification as individual having blue-greenhazel-brown eyes

Classification with a custom Excel file of populations

Classification of multiple profiles with a custom Excel file of populations

Tune up your training/testing set

Classification with the 32 STR training set or a custom Excel file of frequencies

Thorough analysis of population data of a custom Excel file

Profile generator for fixed or custom training sets

Plot some or all the populations of a custom Excel file

We would like to 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.
