Details

The dChip SNP information files for various chip types can be downloaded from http://www.dchip.org/. Put each file in a directory named identically as the corresponding chip type under the annotations/ directory, e.g. annotations/Mapping50K_Hind240/50k hind snp info AfAm june 05 hg17.xls. Note that dChip changes the filename and file format slightly between chip types, but currently the *byChipType() basically searches for files with names consisting of "snp info" or "snp_info". At least for the most common chip types, there is no need to rename the files in order for this class to recognize them.
