Hi,

To create training/testing dataset for MVPA, I'm doing 3dDeconvolve to extract beta values for each condition for each run.
My '-input' in 3dDeconvolve is a preprocessed file that concatenated 16 runs.
I have onset timing txt files for each condition that consists of 16 rows (i.e. for each run) and N columns (i.e. for each trial).

I put '-concat' to let 3dDeconvolve know the concatenated runs, and I used '-stim_times' with row index'{...}' of a timing txt file (e.g., onset_C_test.txt'{1}') to indicate a specific run's onset timing. For example, onset_C_text.txt looks like this:
*
*
*
*
46.18 74.24 102.33 130.36 158.38 186.43 214.45 242.50
*
*
46.12 74.19 102.19 130.19 158.25 186.26 214.32 242.37
46.16 74.17 102.17 130.23 158.23 186.24 214.28 242.29
*
*
46.14 74.14 102.21 130.23 158.24 186.29 214.36 242.36
*
*
*
*



But afni says errors like this:

---

** ERROR: mri_read_ascii_ragged_fvect: couldn't open file /MAINTASK/beh_data/onset_C_test.txt{1}
** FATAL ERROR: '-stim_times 17' can't read file '/MAINTASK/beh_data/onset_C_test.txt{1}' [nopt=129]

---

I'd appreciate if anybody let me know what makes error or any recommendations.
Below is a script that I used.

* ${maeC} is 'onset_C_test.txt'.
