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
