WASHINGTON, DC, Aug. 25 (GenomeWeb News) - Children's National Medical Center will post an analysis tool within one month that will enable researchers to determine how many microarrays they will need to run a particular experiment, according to an CNMC official.
The free tool, called Power Analysis, will be posted on the center's Public Expression Profiling Resource website, an online expression data depository, according to Eric Hoffman, who heads the CNMC's
Hoffman said that there was a need for a tool that would allow researchers involved in clinical trials or exploratory research to "design an ethical experiment" using the appropriate number of samples and "alleviate multiple testing problems" by only running as many arrays as were determined to be necessary.
Hoffman said the tool had been developed with fellow CNMC scientist Jinwook Seo and others, and that it would be public domain. A paper is in the works.
