Hi PT,
I am working with Catherine and can provide you with the information you requested to expedite this query.
Here is the output of each command:
# A
afni -ver
Precompiled binary linux_ubuntu_16_64: Mar 24 2021 (Version AFNI_21.0.21 'Titus')
# B
@FindAfniDsetPath TTatlas+tlrc
/usr/local/afni/bin
# C
afni -no_detach -q -VAFNI_GLOBAL_SESSION=
this command did not actually do anything, it just returned the command line
# D
afni -no_detach -q -VAFNI_ATLAS_PATH=
this command did not actually do anything, it just returned the command line
Regards,
Christine Smith
