Hi AFNI experts,

I'm now using proc.py to process fMRI data following the example 6. The scripts are as follows:
**********************************
afni_proc.py -subj_id subj_task12 \
-dsets pre_task?.nii.gz \
-do_block align tlrc \
-copy_anat pre_anat.nii.gz \
-tcat_remove_first_trs 10 \
-align_opts_aea -cost lpc+ZZ \
-volreg_align_to MIN_OUTLIER \
-volreg_align_e2a \
-volreg_tlrc_warp \
-regress_stim_times left_hand_time.1D right_hand_time.1D rest_time.1D \
-regress_stim_labels lefthand righthand rest \
-regress_basis 'TENT(0,6,4)' \
-regress_motion_per_run \
-regress_censor_motion 0.3 \
-regress_opts_3dD \
-gltsym 'SYM: +lefthand -righthand' \
-glt_label 1 left-right \
-gltsym 'SYM: +lefthand -rest' \
-glt_label 2 left-rest \
-gltsym 'SYM: +righthand -rest' \
-glt_label 3 right-rest \
-regress_est_blur_epits \
-regress_est_blur_errts
**********************************

It can generates the process script and works fine at beginning. However, fatal error occurs as follows when at 3dDeconvolve step:
**********************************
*+ WARNING: !! in Signal+Baseline matrix:
* Largest singular value=2.23282
* 1 singular value is less than cutoff=2.23282e-07
* Implies strong collinearity in the matrix columns!
*+ WARNING: +++++ !! Matrix inverse average error = 0.00488281 ** BEWARE **
** ERROR: !! 3dDeconvolve: Can't run past 2 matrix warnings without '-GOFORIT 2'
** ERROR: !! Currently at -GOFORIT 0
** ERROR: !! See file 3dDeconvolve.err for all WARNING and ERROR messages !!
** ERROR: !! Be sure you understand what you are doing before using -GOFORIT !!
** ERROR: !! If in doubt, consult with someone or with the AFNI message board !!
** FATAL ERROR: !! 3dDeconvolve (regretfully) shuts itself down !!
*******************************

I cannot figure out how the error occurs and not sure to use '-GOFORIT 2'. Could you please help?

BTW, just for your reference, the "regress_stim_times" 1D file I used here are like follows:
*****************
0 2 4 18 20 22 56 58 60 72 74 76 78 80 82 142 144 146 148 150 152 160 162 164 172 174 176 184 186 188 212 214 216 230 232 234 236 238 240 274 276 278 280 282 284 296 298 300 328 330 332 334 336 338
0 2 4 18 20 22 56 58 60 72 74 76 78 80 82 142 144 146 148 150 152 160 162 164 172 174 176 184 186 188 212 214 216 230 232 234 236 238 240 274 276 278 280 282 284 296 298 300 328 330 332 334 336 338

So two run, two rows with stimulate time(TR=2s). I don't know if this kind of file cause the problem or not. I'm not quite sure if the providing stim_time is right. Or something wrong with my gltsym?

Many thanks!


Best regards,
