Greetings,

I'm new to AFNI and Linux and would appreciate any help. I am interested in using align_epi_anat.py and ran the following example code (following the example in -help):

The code:
$ python align_epi_anat.py -anat ~/AFNI_data4/sb23/sb23_mpra+orig -epi ~/AFNI_data4/sb23/epi_r03+orig -epi_base 5

The result:
#++ align_epi_anat version: 1.06
#Script is running:
3dAttribute DELTA /home/xl/AFNI_data4/sb23/epi_r03+orig
#++ Spacing for EPI to tlrc alignment is 3.500000
#Script is running:
3dAttribute DELTA /home/xl/AFNI_data4/sb23/sb23_mpra+orig
#++ Spacing for anat to EPI deobliquing is 0.937500 mm
#++ Removing all the temporary files
#Script is running:
rm -f __tt_epi_r03*
Traceback (most recent call last):

It appears that some file/directory is required but missing?

Thanks.
