Hey Isaac,
Thank you for the comprehensive response. I'm currently on Mac OS 10.7. I believed I installed the mac package I found from the numpy website, it required python 3 which I just use infrequently with a different alias. Quick couple questions. Are there environment or path's I have to set to use Numpy? I didn't read anything of it and the installer did not change my various .bash_rc, .profile, .login's etc.
And for using the function I assume I just create a new function in Numpy with your given script?
Apart from messing around a bit with AFNI's .py's I'm not too familiar with Python so any help is greatly appreciated.
Thanks for the help,
John
