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

To get the geometry matrix and dimensions:
3dAttribute IJK_TO_DICOM_REAL dset_name
3dAttribute DATASET_DIMENSIONS dset_name

To copy one matrix from a dset to another (but I don't think this is what you want to do for your data case here??):
# tcsh syntax
set obliq_matr = `3dAttribute IJK_TO_DICOM_REAL  my_dset`
3dcopy other_dset other_dset_copy.nii
3drefit -atrfloat IJK_TO_DICOM_REAL "${obliq_matr}" other_dset_copy.nii
Above, I copie dthe "other_dset" because refitting the header might do bad, undoable things to it.
