Hey guys,

You are correct that the anat is a T2, it is being used since the slicing matches that of the epi. I used the TT_N27+tlrc template since it is our lab standard and I am not aware of any T2 weighted standard brain templates.

I was curious about using align_epi_anat.py and seeing whether it would put the image into full tlrc space and label the output as such. I gave it a few tries but it seems to have problems with one of the resampling steps even when -resample off option is utilized.

Script + Error message are below. Any ideas?

-Chris
