Hi,
I have a script for afni_proc.py that works on a machine but on another.
The script works perfectly fine with AFNI_2011_12_21_1014 (precompiled macosx_10.6_Intel_64) on Mac OS 10.9.3 (2.26 GHz Intel core 2 Duo).
But with AFNI AFNI_2011_12_21_1014 (Precompiled binary macosx_10.7_Intel_64) running on Mac OS 10.9.3 (2.6 GHz Intel core i5), I get the following error:
"reps '#' is not an int in dset "
Datasets and scripts are exactly the same.
Thank you !
Guillaume
