One study of professional software development teams from a number of different organizations of different sizes found that developers in the best managed organizations had an average of 1.05 defects per 1000 lines of code, […]
Should we rename OpenfMRI? Request for community input
We have been busy in the last year building a new platform that will ultimately serve as the new basis for the OpenfMRI project, supporting both data analysis and sharing. One major change with the new platform is that we will support processing and sharing of datasets that do not include fMRI (such as structural […]
Big problems for common fMRI thresholding methods
A new preprint has been posted to the ArXiv that has very important implications and should be required reading for all fMRI researchers. Anders Eklund, Tom Nichols, and Hans Knutsson applied task fMRI analyses to a large number of resting fMRI datasets, in order to identify the empirical corrected “familywise” Type I error rates observed […]
Reproducibilty and the ease of fooling ourselves
The new study from the Reproducibility Project, published this week in Science, has been getting a great deal of attention. In short, out of 100 attempted well-powered replications of findings from three psychology journals, less than half were found to replicate. Ed Yong has a particularly nice piece at the Atlantic that discusses the results […]
