[VoxBo] Scripting Question

[Ling Wong]

Hi Ben,

If you type   gds -x sample.gds   a file called sample.gds is created that
contains lots of information about these kinds of options.  This is just a
relevant bit copied from that file:

# "newcov trial-effect ,trial_lenth." adds trial effect covariate
# <trial_length> is the length of the trial effect (unit: second)
# default tuype: I; default name: trialfx-<index>
# e.g. the covariates created in this section will be called:
# trial-fx-a, trialfx-2, ...
newcov trial-effect 40
   # I want to shift 3 seconds (3000ms) on each new trial effect covariate
   opetion time-shift 3000
end

There's also something similar if you have variable trial lengths.

Cheers,
Ling
