Dear Tendai, The "GWAS Data Cleaning" vignette that comes with GWASTools shows how to import plain text files (we usually start with the FinalReport files output from Illumina's GenomeStudio) into the NetCDF format used by GWASTools. You will need to define integer chromosome codes for autosomes and sex chromosomes, and then specify these codes when you create objects in GWASTools throughout your analysis (since the default is human with 22 autosomes). You will need the development version of GWASTools (1.5.4 or later), which has support for different numbers of autosomes. It can be found here: In the documentation for the GenotypeData class ("?GenotypeData"), there is an example of how to set up GWASTools with a non-human organism. I am copying the Bioconductor mailing list. Please include bioconductor at if you have any follow-up questions, for the benefit of other package users.
