Part 1:  Population structure

Overview:
  1. Import a SNP dataset in gd_snp format from the Galaxy library.
  2. Find the coverage distribution of the sequence reads for each individual.
  3. Draw a phylogenetic tree for the individuals in the dataset.
  4. Convert and filter the gd_snp dataset for use with subsequent tools.
  5. Run a Principal Components Analysis on the converted SNPs.
  6. Group the individuals using information from the tree and the PCA.
  7. Remove an outlier from the input dataset.
  8. Run the PCA again, this time with group labels.
  9. Graph the ancestry of the individuals.
