AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hi, Gang.

Thanks for the prompt reply. I have a couple of follow-up questions.

Using sub-bricks 4 and 5 as an example:

-- At sub-brick #4 'emot-shape' datum type is short: -11961 to 32767 [internal]
[* 0.000223776] -2.67659 to 7.33248 [scaled]
-- At sub-brick #5 'emot-shape Z' datum type is short: -13331 to 32767 [internal]
[* 0.00084621] -11.2808 to 27.7278 [scaled]
statcode = fizt

You note that "Unlike F-statistics, each t-statistic is paired with the corresponding effect estimate."

My questions are:
1) Does sub-brick 5 contain z-statistics or t-statistics?
2) Can you elaborate what you mean by "effect estimate" here? Is this basically just the difference between the estimated means for the two conditions that are being contrasted (or the estimated mean difference between pairs for w/in subject tests)?

Thanks,
Ruskin
