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 ALL,
I have the problem that when I try to dump out the 64 values per voxel into a file using 3dmaskdump, the dumped values with corresponding spatial coordinates don't match when I upload the file I dumped into AFNI GUI and go to the spatial coordinate position there. The following are the commands I used:
(1) whereami -mask_atlas_region TT_Daemon:right:47 -prefix trmiddle
(2) 3dresample -master DeconIMGAMpulse+tlrc -prefix testRmiddle -input trmiddle+tlrc
(3) 3dmaskdump -mask testRmiddle+tlrc -noijk -xyz -o testRmiddledump
Also if you 3dinfo the files you get:
DeconIMGAMpulse:
-79.5 79.5 3.0 54
-79.5 109.5 3.0 64
-63.5 83.5 3.0 50
trmiddle:
-80 80 1.0 161
-80 110 1.0 191
-65 85 1.0 151
testRmiddle:
-79.5 79.5 3.0 54
-79.5 109.5 3.0 64
-63.5 83.5 3.0 50
The file DeconIMGAMpulse+tlrc is an old file from 2011. I don't know if that makes a difference. What stupid thing am I doing? Thanks for your help!
-Linda
