Terminate Experiment After Elapsed Time X

DCole9 — Thu, 19 Feb 2015 13:52:15 GMT

Hey Inquisiters,
I'm trying to have my experiment terminate itself after expt.name.elapsedtime becomes > a certain duration. I tried doing the following.

<trial>
...
/branch = [if (expt.myexpt.elapsedtime < 810000) block.theblock)]
</trial>
<exp myexptt>
/blocks [1 = theblock]
</expt>

This is giving me the error that block.theblock is the wrong element type. I suspect that is because I am trying to branch to a block from a trial? I have to code my experiment this way b/c my trials refresh on each button press (fills a bar). So I have blocks as my "trials". Is there a way to 'break' the experiment with a certain command or to branch to a block from a trial? Maybe there is something I am missing.

Thanks for your time,
Dan

Thanks for the response Dave. /stop seems suitable for me.

</trial>

You cannot branch from a trial to a block. Branches must be at the same level, i.e. a trial can branch to another trial, a block can branch to another block.

The /stop attribute will *not* interrupt the currently running trial. It will only kick in once the trial terminates.

If you want a *hard* interrupt, use the /timeout attribute.

I discovered the stop command--- seems to work well. I was testing it in my experiment section and set it to stop the experiment after just 1 second. However I noticed that the experiment continues well beyond one second. Does it always finish the current block/trial/etc. before it terminates?
