seq2id: Transfer a nucleotide sequence as a nuID

In lumi: BeadArray Specific Methods for Illumina Methylation and Expression Microarrays

Description

The nuID (nucleotide universal identifier) is uniquely corresponding to probe sequence. The nuID is also self-identification and error checking

Usage

seq2id(seq)

Arguments

seq	a nucleotide sequence composed of A, C, G, T (U).

Details

The nuID is a exact mapping of nucleotide sequence based on Base64 encoding scheme. A character set A-Z, a-z, 0-9, "\_" and "." is used to represent to the base-64 numbers of 0-63. The first character of nuID is a checking code, which provide information of both the number of padded "A"s at the nucleotide sequence and error checking. Please refer to reference for more details.

Value

A string represents nuID
