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

A related question, we have three output datasets (from 3dttest) and we have been creating an "or" mask using the following code:

3dmerge \
-prefix OR_step1_FDR \
-2clip -4.5 4.5 \
-gcount \
all_control_tvs0+tlrc'[1]' all_impulsive_tvs0+tlrc'[1]' all_restrained_tvs0+tlrc'[1]'

And then we used 3dmerge to cluster the resulting OR mask:

3dmerge \
-prefix OR_MASK_FDR_clust200 \
-1clust_order 0 200 \
OR_step1_FDR+tlrc


We're thinking we would like to try to use AlphaSim to accomplish a similar end. I've only used AlphaSim on individual datasets (but in this case we'd like to make an OR mask based on three separate datasets, and have that OR mask be clustered to correct for false positives) In other words, what dataset should we provide as our input to AlphaSim?

. Any advice on how we should proceed?
