Jetset: selecting an optimal microarray probe set to represent a gene

Summary:
On Affymetrix gene expression microarrays, a given gene may be detected by multiple probe sets which may deliver inconsistent or even contradictory measurements.
Therefore, obtaining an unambiguous expression estimate of a pre-specified gene can be nontrivial.
We developed scoring methods to assess each probe set for specificity, coverage, and degradation resistance.
We used these scores to select the optimal probe set for each gene, and thus create a simple one-to-one mapping between gene and probe set.
News
July 30, 2015: jetset is now on GitHub.
July 23, 2015 - After an unexplainable 5 year delay, jetset is now available on CRAN!
Release information
The jetset algorithm utilizes two sources of external data:
- mRNA sequences from
RefSeq
- RefSeq-to-gene mappings from the R/Bioconductor package
org.Hs.eg.db.

Data in CSV format
Current versions can be downloaded from the following table.
The data in the CSV files and the data in the R package are essentially identical.
The CSV files are intended for people who don't use R.
Previous versions can be downloaded here.
Users of these files may be interested in a brief explanation of the data format.
