The new ETAC method for cluster-thresholding is now ready for use, in program 3dttest++.
The slides from my presentation today (26 July 2017) at the NIH are available: https://drive.google.com/file/d/0B6Sn11ZTBrhvOGJLek9iWWRkOTg/view?usp=sharing
The help for 3dttest++ contains more details about how to use this method: https://afni.nimh.nih.gov/pub/dist/doc/program_help/3dttest++.html
ETAC is a method that applies multiple per-voxel thresholds, allows you to use multiple levels of blurring, and does spatially variable cluster-size (or other Figure Of Merit) thresholding. To use it, you need a recently updated copy of AFNI – by “recent”, I mean within the last week or so.
Good luck, and be careful out there.
