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, Prateek-

How about make a text file with all xyz coords (first 3 cols) and ROI values (4th col), called file_xyz_and_values.txt, which could look like, say:
-17  47 -48 1
 47 -27  -7 2
 -7 -80 -12 35
 52 -19 -29 4
-29   5 -12 12
Then, 3dUndump that text file, and you can see the preferences given by ordering in cases of overlap:
3dUndump                              \
    -overwrite                        \
    -xyz                              \
    -orient RAI                       \
    -prefix M2.nii.gz                 \
    -master REFERENCE_DSET     \
    -datum byte                       \
    -srad 10                          \
  file_xyz_and_values.txt
... so you can control which seed/ROI "wins" in cases of overlap?
