PHRED

(in DNA SEQUENCING) a computer program for DNA sequence traces, that reads the trace, ‘calls’ the bases and assigns a quality score to each base. For the quality score, peaks round each base are examined. A quality score of X corresponds to an error probability (i.e. probability that the base called is wrong) of 10; a score of 30 (10–3 error probability) corresponds to 99.9% accuracy for the base call.

The likelihood of a given sequenced base being correct is measured by the Phred (or Q) score.
Using the pipeline generation system EGene, the sequences were filtered by quality using phred values, masked against primers EUB r1387 and EUB f933 and vector sequences (pCR2.1 TOPO-TA), trimming and selected by size (>100 bp).
Each base sequencing error can be judged by [Q.sub.phred] (Phred score), which is given by a model of prediction base judging error probability during Base Calling.
This resulted in a total of 308 sequences (75 sequences from RIB-A D, 70 sequences from RIB-B D, 75 sequences from RIB-A T, and 88 sequences from RIBB T) with high Phred quality (>20) and size over 400 bp.
