1. Example of running the encoding function "seq2id" and decoding function "id2seq"
## Example:
   source(coding.R)
   seq <- 'ACGTAAATTTCAGTTTAAAACCCCCCG'
   id <- seq2id(seq)
   id
   id2seq(id)

2. The encoding function "seq2id" and decoding function "id2seq" were also included in the data package Mouse.lumi and Human.lumi

3. The usage of data package Mouse.lumi and Human.lumi is the same as the affy data packages in Bioconductor.

4. These functions will be included in the lumi package, a package of preprocess the Illumina microarray dta.
