Why did the old Folly end now, and no later? Why did the modern Wisdom begin now, and no sooner?

-Rabelais, Prologue to Book V

=======================

Academia, like our nation's morals, seems to be forever in peril. When I first heard of the replication crisis - about how standards are so loose that a scientist can't even replicate what he ate for breakfast three days ago, much less reproduce another scientist's experiment - I was reminded of my grandpa. He once complained to me that colleges today are fleshpots of hedonism and easy sex. Nonsense, I said. Each year literally tens of students graduate with their virtue intact.

Once you've loaded up a contrast in SPM and thresholded it at a particular correction threshold, such as cluster corrected or FWE corrected, you can then simply save that image into a .hdr/.img file for use in another viewer, such as MRIcron. Just push the save button in the results window, and there you have it. This image can also be used for other purposes, such as doing an ROI analysis within only those voxels passing a corrected threshold for a given contrast.

Same image, but saved out into .hdr/.img format and viewed in MRIcron.

In case it isn't clear how to do this from the above, I've also made an instructional video about how to do it, which - if you can believe it - was done in only one take. I have my little victories.
