Thanks.

I am trying to test a set of 100 timing sequences for the optimal sequence similar to the @stim_analyze script. When I enter the following, I get the error 3dD.nodata.${iter}: Ambiguous. I am not sure why this is since the syntax seems to be the same as in @stim_analyze.

# experiment parameters
set ts = 256
set stim = 16
set num_on = 8

# execution parameters
set iterations = 100
set seed = 1234567
set outdir = stim_results
set LCfile = $outdir/LC_sums

foreach iter ('count -digits 3 1 100')
@ seed = $seed + 1
