Figure 1From: Error-correcting properties of the SOLiD Exact Call ChemistryArchitecture of the SOLiD ECC encoder. The architecture of the convolutional code for the SOLiD ECC consists of two streams. The nucleotide sequence a 1,a 2,… is passed through the encoder, progressing one position at a time, and the color obtained from the additions and multiplications indicated is emitted from each stream. The top ‘color stream’ is that produced by the two-base-encoding chemistry and the bottom ‘SOLiD ECC stream’ is punctured so that only every fifth color member of the sequence is used.Back to article page
