MRI software bugs could upend years of research

Now, boffins from Sweden and the UK have cast doubt on the
quality of the science, because of problems with the
statistical software: it produces way too many false
positives. In this paper at PNAS, they write: "the most
common software packages for fMRI analysis (SPM, FSL, AFNI)
can result in false-positive rates of up to 70%. These results
question the validity of some 40,000 fMRI studies and may have
a large impact on the interpretation of neuroimaging results."
For example, a bug that's been sitting in a package called
3dClustSim for 15 years, fixed in May 2015, produced bad
results (3dClustSim is part of the AFNI suite; the others are
SPM and FSL).
