Hi-

I have a question. I have data in RPI format, and so was going to use an RPI-resampled standard TT_N27 data set as a Talairach base in afni_proc.

I resampled the dataset:
$ 3dresample -orient RPI -prefix TT_N27_RPI -inset TT_N27+tlrc.HEAD

I have the dataset in directory: ~/REF_TEMPLATES/ .

And my afni_proc command is based on one of the examples:

afni_proc.py -subj_id subj123_D                                \
                  -dsets 2*_EPI.nii.gz  \
                  -copy_anat THR_ANAT.nii.gz \
                  -blocks despike tshift align tlrc volreg blur mask regress \
                  -tcat_remove_first_trs 3                                   \
                  -volreg_align_e2a                                          \
                  -volreg_tlrc_warp                       \
                  -tlrc_base TT_N27_RPI+tlrc \
                  -align_opts_aea -giant_move \
                  -mask_segment_anat yes                                     \
                  -regress_censor_motion 0.2                                 \
                  -regress_censor_outliers 0.1                               \
                  -regress_bandpass 0.01 0.1                                 \
                  -regress_apply_mot_types demean deriv                      \
                  -regress_ROI WMe CSFe                                      \
                  -regress_run_clustsim no                                   \
                  -regress_est_blur_errts

However, when I run the above command, I get the following error:

** failed to find tlrc_base 'TT_N27_RPI+tlrc' for group mask

In my ~/.afnirc file, I have the following set to point to the said directory:
AFNI_TTATLAS_DATASET = ~/REF_TEMPLATES/
AFNI_GLOBAL_SESSION = ~/REF_TEMPLATES/
AFNI_SUPP_ATLAS_DIR = ~/REF_TEMPLATES/
(with and without final '/')

I have also tried setting the base using absolution paths, as well:
-tlrc_base ~/REF_TEMPLATES/TT_N27_RPI+tlrc \
-tlrc_base /home/paul/REF_TEMPLATES/TT_N27_RPI+tlrc \
with no success.

What am I doing wrong for using this (or any other) data set as a tlrc_base, for the final errts results to end up?

Thanks,
pt
