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

Update: You were right; it was a memory problem running 3dttest++ on the command line. I submitted the code via the sge scheduler and eventually got it to complete after increasing the memory limit. However, now there are no more significant voxels :(

The exact command that I used was

3dttest++ -prefix stat.6.covary_ACM -AminusB -setA Vrel FP OLSQ.FP.betas+tlrc.HEAD[Vrel#0_Coef] FR OLSQ.FR.betas+tlrc.HEAD[Vrel#0_Coef] 
FT OLSQ.FT.betas+tlrc.HEAD[Vrel#0_Coef] FV OLSQ.FV.betas+tlrc.HEAD[Vrel#0_Coef] FX OLSQ.FX.betas+tlrc.HEAD[Vrel#0_Coef] 
GF OLSQ.GF.betas+tlrc.HEAD[Vrel#0_Coef] GG OLSQ.GG.betas+tlrc.HEAD[Vrel#0_Coef] GI OLSQ.GI.betas+tlrc.HEAD[Vrel#0_Coef] 
GK OLSQ.GK.betas+tlrc.HEAD[Vrel#0_Coef] GM OLSQ.GM.betas+tlrc.HEAD[Vrel#0_Coef] -setB Arel FP OLSQ.FP.betas+tlrc.HEAD[Arel#0_Coef] 
FR OLSQ.FR.betas+tlrc.HEAD[Arel#0_Coef] FT OLSQ.FT.betas+tlrc.HEAD[Arel#0_Coef] FV OLSQ.FV.betas+tlrc.HEAD[Arel#0_Coef] 
FX OLSQ.FX.betas+tlrc.HEAD[Arel#0_Coef] GF OLSQ.GF.betas+tlrc.HEAD[Arel#0_Coef] GG OLSQ.GG.betas+tlrc.HEAD[Arel#0_Coef] 
GI OLSQ.GI.betas+tlrc.HEAD[Arel#0_Coef] GK OLSQ.GK.betas+tlrc.HEAD[Arel#0_Coef] GM OLSQ.GM.betas+tlrc.HEAD[Arel#0_Coef] 
-paired -covariates covary.toe.gap.txt -ETAC -ETAC_blur 0 4 -ETAC_opt sid=1:hpow=0:name=test1:pthr=0.01/0.001/10:fpr=9 
-mask mask+tlrc

The purpose of this was to test if the issue can be replicated on your data with blurring. I will try hpow=2 to check significance but if there's no voxels significant, it makes it very difficult to debug if the same exact settings can't be tested for both datasets. :(
