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

I've tried 3dTcorr1D (and 3dfim+) and it looks like it works, but I'm not sure if what I am doing is correct. Below is my script so far: 
whereami -mask_atlas_Region TT_Daemon:left:precuneus -prefix Lprec
3dWarp -prefix L_precunn -tta2mni Lprec+tlrc
3dresample -master errts.subj.fanaticor+tlrc. -inset Lprecunn+tlrc -prefix L_precuneusM
3dmaskave -mask L_precuneusM+tlrc -quiet errts.subj.fanaticor+tlrc. > L_precun.1D
1dBandpass 0.01 0.1 L_precun.1D > L_precunn.1D
3dTcorr1D -prefix Left_precuneusCorr -mask mask_brain+tlrc. errts.subj.fanaticor+tlrc. L_precunn.1D
I know that by default, 3dTcorr1D uses pearson correlation coefficient. The highest overlay threshold value is 0.56, but shouldn't the correlation with itself be one of the highest, at least 0.8?


Edit: I think I figured out the problems in my script. Thank you.
