From: Improved base calling for the Illumina Genome Analyzer using machine learning strategies
Comparison of quality scores for the 51 cycle PhiX control lane data. Quality scores reported by Bustard, AltaCyclic and Ibis are compared in PHRED scale. For all three base callers, we considered only quality scores reported with 100,000 and more observations. Calculating the deviation from the optimal line, Bustard has a root mean square deviation of 84.9, AltaCyclic of 19.3 and Ibis of 0.9.
