Abstract
I will describe two distinct research projects from my group at EBI . In the first, I will show how a simple flaw in progressive multiple alignment algorithms has led to alignment errors for many years. The error is easily corrected; scientists’ expectations of what a good alignment should look like may take longer to change. In the second, I will describe how the Solexa/Illumina Genome Analyzer sequencing platform works, some of the processes that lead to errors in its short-read sequences and how inference based on mathematical modelling of these errors has led to improved results.
