Thanks Rick,

Actually - my lab just got a new Mac OS X version 10.6.6 Desktop and I have successfully downloaded FINK and AFNI according to the instructions on [afni.nimh.nih.gov]

I used the latest fink for 10.6 and 10.7 (source install) [www.finkproject.org] and followed the directions there.

I know I installed fink properly because when I type in FINK, I get:
Fink 0.31.0

Usage: fink [options] command [package...]
fink install pkg1 [pkg2 ...]

Common commands:
install - install/update the named packages
remove - remove the named packages
purge - same as remove but also removes all configuration files
update - update the named packages
selfupdate - upgrade fink to the lastest release
update-all - update all installed packages
configure - rerun the configuration process
list - list available packages, optionally filtering by name, see
'fink list --help' for more options
apropos - list packages matching a search keyword
describe - display a detailed description of the named packages
index - force rebuild of package cache
validate - performs various checks on .info and .deb files
scanpackages - rescans the list of binary packages on the system
cleanup - reclaims disk space used by temporary or obsolete files
show-deps - list run-time and compile-time package dependencies

Common options:
-h, --help - Display this help text.
-q, --quiet - causes fink to be less verbose, opposite of --verbose
-V, --version - display version information
-v, --verbose - causes fink to be more verbose, opposite of --quiet
-y, --yes - assume default answer for all interactive questions
-b, --use-binary-dist - download pre-compiled packages from the binary
distribution if available
--no-use-binary-dist - Opposite of use-binary-dist

However, after installing AFNI (64 bit) - I get bash : afni: command not found..

What am I doing wrong? Any suggestions?

Thanks
