Alignments from Thornton, Bachtrog, and Andolfatto (2006) X-chromosomes and autosomes evolve at similar rates in Drosophila - no evidence for faster-X protein evolution. Genome Research 16: 498-504

Alignments and annotations from Thornton and Long (2005) Excess of Amino Acid Substitutions Relative to Polymorphism Between X-Linked Duplications in Drosophila melanogaster. Mol. Biol. Evol. 22: 273-284. This contains the alignments used for summary statistics, and the annotation files compatible with "polydNdS" in my analysis software package. It currently does not contain the files used for McDonald-Kreitman tests, or the analysis of gene conversion between paralogs. For the moment, those are available on request to Kevin Thornton.
