Sri Gurujis-

We really like the new QC options you've made available via afni_proc. Two questions emerge:

1. Might we expect to see a correspondence between the qc_00_ve2a_epi2anat.???.jpgs and the "anat/EPI mask Dice" coefficient generously provided in the out.ss_review.*.txt file? I don't see documentation pointing to what the Dice coef is but I'm assuming it's something like the Sørensen–Dice coefficient?

2. Is there a way to obtain something similar to the Sørensen–Dice coefficient but for indexing the similarity between the warped anatomical and the template to which it was warped?

I'm asking the last question because we're doing QC on a large consortium-dataset of ~1500 braaaaiiiins! (happy Halloween) and it would be nice to have a handy summary index of the quality of the anat2temp warp for each subject.

Regards,

Paul
