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

How about using 3dcalc in the way you say to create a copy of the original for all included voxels? Then create a summed image with 3dTstat -sum. Then use 3dcalc to divide by the total 1's in your censor file.

3dcalc -a data+orig -b 'templist.1D' -expr 'a*b' -prefix 'censordata'
3dTstat -sum -prefix testsum censordata+orig
set nvals = `awk 'BEGIN {sum=0}; {sum=sum+$1}; END {print sum};' templist.1D`
3dcalc -a testsum+orig -expr "a/$nvals" -prefix censored_avg
rm testsum+orig.*
rm censordata+orig.*

There's no doubt more than one way to do this, but there you go.
