Functional MRI that shows human brain in action is growing
in use within academic and research communities intent on uncovering the inner
workings of the brain, says Russell Poldrack of Dept of Psychology, Stanford U.
tells a lecture audience at Computer Information Science and Engineering series
at NSF. But there are issues. The approach is costly, and it is not clear
how reproducible big data analysis of the brain action is. Reproducibility of
experiments using the scientific method is very important, but when R programs
run on different machine configurations, different analytical results may emerge.
Poldrack and others are working with software containers and virtual machines
and registries to address this issue of computational reproducibility. - Jack Vaughan
