Dear AFNI forum members,

I am trying to generate preprocessing scripts from afni_proc.py that was working properly in the past. However, recently, I was prompted with an error as shown below.

** applying default -blur_size of 4.0 mm FWHM
-- tcat: reps is now 283
-- volreg: base/sub indices are 0, 2
++ volreg: aligning to isotropic 3 mm voxels
Traceback (most recent call last):
File "/Users/lguo15/abin/afni_proc.py", line 2682, in <module>
rv = run_proc()
File "/Users/lguo15/abin/afni_proc.py", line 2668, in run_proc
rv = ps.create_script()
File "/Users/lguo15/abin/afni_proc.py", line 1642, in create_script
self.make_exec()
File "/Users/lguo15/abin/afni_proc.py", line 2241, in make_exec
os.chmod(self.script, 0755)
OSError: [Errno 13] Permission denied: 'proc.p48'

It denied me from generating a full preprocessing script for individual participant's data. I have not encountered problems like this in the past.

I have recently updated my computer to el capitan. I have resolved the issues with python that was described in this thread (http://afni.nimh.nih.gov/afni/community/board/read.php?1,149775,149775#msg-149775). So things were working properly. But after I preprocessed my data using the preprocessing scripts generated from afni_proc.py, I found out some alignments weren't great. So I went back and added -big_move -partial_coverage to the preprocessing scripts to correct the misalignment. It worked fine for one person but the error popped up after that.

Could you please help me with this?

Thank you very much!

Best,
Li
