Protocol for genomic DNA random labeling

Xu Zhang and Yan Li’s updates to the labeling methods for SNP/tiling arrays

              including cDNA labeling

Yan Li’s updates for AtSNPtile1 10/25//08

 

“readcel.R” and “readcel2.R” function hto read in ASCII text .CEL file and perform spatial correction (example)

“SFP.R” script to normalize data and call Single Feature Polymorphisms

                      (quality control “pairs.jpg”, “cor.image.jpg”) LerSFP

“deletions.R” script to call potential deletions via linear clustering

                           example deletion.jpg, program: lcluster

                           deletions in Ler, graphical display

                           SFP in Ler

“Map.R” script to perform Bulk Segregant Analysis or eXtreme Array example map.jpg

 

scripts can be pasted into R line by line.

Download R from www.r-project.org and

Bioconductor from www.bioconductor.orgaffy” package required)
