Running SAM
- SAM is available for download online at http://www-stat.stanford.edu/~tibs/SAM/ for academic and non-academic users after completion of a registration step.
- SAM is run as an Excel Add-In, and the SAM Plot Controller allows Customization of the False Discovery Rate and Delta, while the SAM Plot and SAM Output functionality generate a List of Significant Genes, Delta Table, and Assessment of Sample Sizes
- Permutations are calculated based on the number of samples
- Block Permutations
- Blocks are batches of microarrays; for example for eight samples split into two groups (control and affected) there are 4!=24 permutations for each block and the total number of permutations is (24)(24)= 576. A minimum of 1000 permutations are recommended;
the number of permutations is set by the user when imputing correct values for the data set to run SAM

Famous quotes containing the words running and/or sam:
“Andrews: Do you mind if I ask a question frankly? Do you love my daughter?
Peter: Any guy that’d fall in love with your daughter ought to have his head examined.
Andrews: Now that’s an evasion.
Peter: She grabbed herself a perfect running mate. King Westley! The pill of the century. What she needs is a guy that’d take a sock at her once a day, whether it’s coming to her or not.”
—Robert Riskin (1897–1955)
“I can’t hide it any longer. I love you. It’s the old story, boy meets girl—Romeo and Juliet—Minneapolis and St. Paul!”
—Robert Pirosh, U.S. screenwriter, George Seaton, George Oppenheimer, and Sam Wood. Dr. Hugo Z. Hackenbush (Groucho Marx)
