 Custom CDF

 

  
 Oligonucleotide probes on GeneChips are reorganized based on the latest genome and transcriptome information. In addition to custom CDF files for different target definitions, GeneChips and data analysis platforms, we also provide 1) a probe mapping file that matches individual probes in the custom CDF file and the corresponding Affymetrix CDF file; 2) a grouping file that can be used to find all targets (exons, transcripts) represented by the same probe set. The grouping file also contains the probe set spanning range on genome or transcripts to facilitate RT-PCR primer design.  Click here for the detailed description of these CDF files

We prepare redefined custom CDF files for different platforms for user download
 
 
NCBI Geo data can be used to test different CDFs, user name/password is public/public
 
 
Find probe content and genomic location in given probe sets
 
 
For match probe sets across different GeneChip definitions and species
 
 
So far there are four unique tools in this package, which are for celfile uploading, celfile converting, celfile splitting and Cdf probe filtering.
 
 
The package is designed to eliminate a list of undesirable probes from the corresponding GeneChip. Currently we provide allele-specific probe lists within this package and users can remove SNPs based on location of the allele on the probe as well as available heterozygosity information from dbSNP126.
