Hi Gang,

Hope that I post the message successfully on the message board this time.

I would like to clarify how to generate the time series at ROI and the covariates for 1dGC. My expt has 3 language tasks (A, B, C) this time. I use the following in the previous deconvolution analysis:

3dDeconvolve -input run001_norm+orig run002_norm+orig -polort 3 -num_stimts 9 \
-stim_times 1 A_stim_times.01.1D "TENT(0,16,8)" -stim_label 1 TaskA \
-stim_times 2 B_stim_times.02.1D "TENT(0,16,8)" -stim_label 2 TaskB \
-stim_times 3 C_stim_times.03.1D "TENT(0,16,8)" -stim_label 3 TaskC \
-stim_file 4 mc.1D'[1]' -stim_label 4 roll -stim_base 4 \
-stim_file 5 mc.1D'[2]' -stim_label 5 pitch -stim_base 5 \
-stim_file 6 mc.1D'[3]' -stim_label 6 yaw -stim_base 6 \
-stim_file 7 mc.1D'[4]' -stim_label 7 dS -stim_base 7 \
-stim_file 8 mc.1D'[5]' -stim_label 8 dL -stim_base 8 \
-stim_file 9 mc.1D'[6]' -stim_label 9 dP -stim_base 9 \
-TR_times 1s \
-iresp 1 subj1_TaskA_irf \
-iresp 2 subj1_TaskB_irf \
-iresp 3 subj1_TaskC_irf \
-gltsym diff_TaskA1D -glt_label 1 TaskA \
-gltsym diff_TaskB.1D -glt_label 2 TaskB \
-gltsym diff_TaskC.1D -glt_label 3 TaskC \
-gltsym diff_TaskA_TaskB.1D -glt_label 4 TaskA-TaskB \
-gltsym diff_TaskA_TaskC.1D -glt_label 5 TaskA-TaskC \
-full_first -fout -tout \
-bucket subj1_decon -fitts subj1_fitts \
-xjpeg subj1_xmat.jpg -x1D subj1_xmat.x1D \
-cbucket subj1_cdecon

As I would like to focus on the connectivity for TaskA, I just wonder whether the following steps are correct:
(1) Concatenate run001_norm+orig run002_norm+orig and adwarp to Talairach space
(2) Extract the time series of multiple ROIs from the concatenated +tlrc in (1).
(3) Construct the regressors for TaskB and TaskC.
I have question for this part. As I previously used the tent function "TENT(0,16,8)" for stimulus timing, I couldn't find an option in 'waver' command to generate such the task regressors.
(4) Concatenate the columns of TaskB and TaskC regressors with the motion regressors in a multi-column covariate file.
(5) Then run 1dGC.R

Are the steps correct and how to solve the waver problem? Any better suggestions for the extraction of time series for ROIs and covariates?

Thank you very much for your help in advance.

Cheers,
Phoebe.
