Andreas Schroeder and colleagues, BMC Molecular Biology 7, article 3, 31 January 2006; DOI 10.1186/1471-2199-7-3. The Abstract, Feature selection, Discussion and Figure 8 describe a learned multi-feature score from RNA electrophoresis traces rather than a single ribosomal-peak ratio. The scale runs from 1 to 10, with larger values assigned to better integrity. The score is not a direct fraction of intact molecules. First-author spelling follows the original byline; no identification with similarly named mathematicians is made.
Additional locators: Table 1 partitions 1339 electropherograms into 937 training and 402 test records.
