Paul, sorry, it was a long day for me. I indeed made a typo, hence AFNI could not find one file.
Here is the new output:
Resample_Yeo7N_1000ribbon.nii
1 1 1 1 1 ACW_Awake_Global.nii
1 1 1 1 1 Resample_Yeo7N_1000ribbon.nii
Note that this output (the ACW_Awake_Global.nii file) was generated after I multiplied the y-coordinates with -1 in Python, leaving the x and z coordinates untouched. By untouched, I mean that I extracted those with the "-xyz" command in 3dmaskdump.
