Hi--

I'm an old user of DRT (v2006), but a new user of v2010. I run ERP studies and have used the TTLecho function to allow me to send a TTL code based on a subject's response. However, I cannot...

I just upgraded to v2010 from v2006, but wonder if that was an error. I'm having quite a few problems, no doubt related to Windows 7. Here is one strange problem, an "invalid cast exception error."...

Any responses to this thread? I too am getting the same trial range error--and I just bought v2010; never had such problems with v2006. Please help!

Hi Yeon, Melissa, & Bijoux--

I hate to sound like a broken record, but have any of you programmed the IGT into DirectRT? If so, would you mind sharing?

Thanks,

Michael Inzlicht

Hi-- I think I have finally found a way to make this work, but I need to verify that DRT can handle this accurately. The first step is to get the exact time I need the TTL to be inserted in the...

That's really too bad...

Is there any way this option can be programmed in? I realize this is a difficult problem, so another option is that I can pay for Empirisoft's programming services to...

Not sure what happened there; I thought I attached everything. I've now attached the input file, a stim folder (with instructions and .avi file), and the style file.

I'm using the latest V2006...

I have finally come around to trying this, and it didn't work for me either. It seems like the empty stim (~) is replacing the video so that the video only shows for a short period of time (a few...

yes this is correct. either all of cong first or all of incong first, as long as they stay together within.

Hi.

I ran a study last Fall where I administered a Stroop. In this particular version I needed to randomize both within and between groups. That is, I had to randomize incongruent and congruent...

Hi.

I need to modify a go/nogo task (which I already have) and I am having some trouble. In the task, I will be presenting stimuli to which the participants respond (or not). This I can already...

OK. Let me see if I understand the logic. Let's say I want to show a 15 second movie, and I want a TTL sent at 9.8 seconds. To do this I would show the movie with a time of 0, and then send an empty...

Unfortunately that won't work. We use TTLs for an EEG system and my EEG hardware only recognizes the start of a TTL... Is there any way to "hardcode" a TTL into a movie? Any other way around this? I...

I'm trying to create a movie and then have a TTL signal be sent at a specific moment during the movie (e.g. when the filmed person says "welcome"). Is there any way I can embed a TTL in a movie? If...

Hi,

I bought a button box from you guys a few years ago and have been very happy with it. I just moved labs, though, and now I can't get the button box to work on the same computer. Assuming that...

I've created a go/no-go input file for use with an EEG, meaning that I'm sending TTLs to a second computer. I've just started collecting data and noticed that my no-go trials are often followed by...

Yes, you're right--it would be impossible to give feedback to a "no-go" response. However, I would like to give speed feedback for the "go" responses. For example, I'd like to tell subjects to go...

I'm trying to create a go/no task and am having some problems. I know about the -1 parameter and have seen the GNAT support information. The problem I am running into is that I need my task to...
