Hello,

I am trying to create a random timing generation similar to example # 8. I have 2 sets of stimuli (expt and control) which both have A and B parts. I need to create a fixed ordering in that trial A needs to be followed by B, but the expt & control conditions can be random, as long as they do not interrupt A and B. I have 36 stim for expt condition and 20 for control. The A trials last 3 seconds followed by B trials that last 4 seconds.

When I enter the following:

make_random_timing.py -num_runs 1 -run_time 692 \
-num_stim 4 -num_reps 36 \
-stim_labels exptA exptB controlA controlB \
-stim_dur 3 4 3 4 \
-ordered_stimuli exptA exptB controlA controlB \
-pre_stim_rest 10 -post_stim_rest 10 \
-show_timing_stats -seed 31415 -prefix stimesH \

I get the writing timing files:

writing timing file: stimesH_01_exptA.1D
writing timing file: stimesH_02_exptB.1D
writing timing file: stimesH_03_controlA.1D
writing timing file: stimesH_04_controlB.1D

Along with the ISI statistics. However, I cannot figure out how to verify the stimulus order. That is, the following command is not running:

timing_tool.py -multi_timing stimesH*.1D \
-multi_timing_to_events events.stimesH.txt \
-multi_stim_dur 3 4 3 4 \
-tr 1.0 -min_frac 0.5 -per_run -run_len 692 \

All that outputs is:

timing_tool.py -multi_timing stimesH*.1D \
-multi_timing_to_events events.stimesH.txt \
-multi_stim_dur 3 4 3 4 \
-tr 1.0 -min_frac 0.5 -per_run -run_len 692 \ ? -multi_timing_to_events events.stimesH.txt \
? -multi_stim_dur 3 4 3 4 \
? -tr 1.0 -min_frac 0.5 -per_run -run_len 692 \
** -run_len takes only <type 'float'>s, have: ['692', ' ']
** mulit_timing_to_events requires -run_len

Can someone help me with how to get the timing tool to display the output timings for this example?

Many thanks in advance!
