Ah. I'm fairly positive that the problem may be arising because the Virtual PC's emulation isn't capable of giving DirectRT full access to the machine's (non-virtual) graphics hardware. If this is...

Rramos,
Does the folder with your experiment contain a style file or does it use the default style file? I would first check to make sure the experiment's style file is included in the same...

Added to the task list -- we should be able to accommodate this request in the 2010 version. Blair; should we keep a toggle(able) option to enable or disable the feature?

What are your thoughts...

Yeah -- it seems .CSV files have a limitation with character input. I think we might be able to provide a simple and quick fix into the 2010 version of the software to migrate this request into a...

"The licensing dll package you sent me yesterday did work to fix the problem. Thanks for your help."

That's peculiar --
Have you tried creating a questionnaire with only a single continuous on-line rating item (and nothing else)?

The 2010 beta build contains an option to render the graphics in a window, rather than fullscreen; however, I'm not sure that this feature is an ideal fix for the problem.

It may be helpful to...

Since DirectRT treats animated .GIF files like video files, you may need to include the stimuli that is underneath with the .GIF.

If willing, it may be worth looking into DirectRT 2010, as the new...

I think I understand --

You may want to try embedding the game into the background and using the duration parameter (e.g. d360) to cause the questionnaire to automatically continue. Do you think...

This is interesting.

I wasn't aware of this; however it seems as though the 2008 version (and previous) contains a restriction on how high you can set the font size. It appears that it will go no...

I'm thinking that alteration to the .CSV files may fix the problem.

In your .CSV files you may have time columns that use the following syntax: rt:42,54 (42 is for the left shift key, and 54 is...

I need to have a lexical decision task in which they press the left shift key for a non-word and the right shift key for a word. My question is:
How do I get Direct RT...

Cheryl;
With a little creativity, you should be able to create an experiment file within MediaLab that integrates your requirements; however, it sounds like you may want to take a look at DirectRT,...

Using the experiment duration parameter (e.g. d-300) with your experiment will allow for a countdown timer to activate while a questionnaire is in progress.

To record where the user navigates on a...

Heath;
I think I understand what you're trying to do.

Within this post I've attached two files:

• cursor.zip is an edited version of the sample file:
'C:\DirectRT\Samples\6...

The next build is ready.
To install, try the following:

1. Right-click the DirectRT desktop icon and select 'Run as Administrator' from the menu that opens. This will launch the software with...

Installing an on-board graphics card should fix the problem.

Just about any on-board graphics card you can find will work.

The manual notes:


This recommendation includes just about any...

First of all - thank you for your answers and help.

Unfortunately, although I downloaded the updates and tried to change the resolution and such, the problem...

We've further contemplated the issue and have a few more suggestions to add.

First, I would recommend seeing if altering the position of the video reduces or removes the flickering. From here, you...

(Noam -- I hope it's ok if we redirect the email thread here)

It seems that the most likely reason for this error (that I can think of) could be due to the display device.

If this is the case...

This error has been patched within the newest build of the beta.

If you're still experiencing this error, please contact us at our support address to upgrade your copy of DirectRT.

Ah, thank you for uploading your input file -- we've been able to locate where the bug may be arising from.

We'll do our best to get you an updated build to install and use on Friday.

If your...

Let's see --

What version are you running?
Could you post a copy of the input file that is causing problems?

Hi Joe,

It would seem that the software is running into a problem while trying to access the file 'barebones.drt'.

It may be worth trying the following to troubleshoot the error:

- Make sure...

Hm. I'm not sure if a threshold detection experiment has ever been conducted; however I would be glad to provide as much information as I can on setting up an experiment that utilizes subliminal...

Unfortunately, DirectRT doesn't yet support the feature to compare and alter the design of a study based on the received user variables. MediaLab supports this feature with the help of Excel; however...

Hm - First, I would recommend trying the following:
1. Back up your data.
2. Once the data has been backed up, try deleting the original data folder.
3. Run the experiment again and see if the...

Both MediaLab and DirectRT have the functionality to playback a video and detect when the response time is given; however DirectRT will yield a more accurate result.

It's good to hear that you...

The following image formats are usable within both MediaLab and DirectRT:
".bmp"; ".png"; ".jpg"; ".gif"; ".tga"

In regards to video files --
If it runs in Windows Media Player, it should work...

In order to simplify the system as much as possible, only an FTP connection is needed - you will not be required to install any server-side languages.

Files stored on the FTP account are encrypted...

Hi Eyal --

It would seem that the problem you're experiencing resolves itself if you remove all upper-case lettering from within your responses.xls file and the variable names within your...

Ah! That makes sense.

Yes - the reason for this is because the file is encoded as a collection of data. The data is read by a tool that can interpret the format.

.JPG data is encoded in a much...

Ah - yes. That's correct. My apologies, I didn't quite think that one all the way through.

While it is possible to change the actual graphics used, the underlying functions will still be located...

Yes - to do so, navigate to the folder:
C:\MediaLab\Graphics

Try swapping the names of the files 'goback.bmp' and 'continue.bmp'. Additionally - you may have to edit the image to change the...

yepapey ;

It may be worth re-saving your stimuli to see if the problem is arising due to an alpha layer being present within the bitmaps. If the bitmaps contain an alpha layer, they will not...

Hello lmris -

It may be worth trying to see if Eprime's forums contain any information on how to run an experiment file from the command line.

I've investigated this issue; however I can't seem...

Hello Jaan -

Do you know what version of DirectRT that you're using?

To check, simply navigate to the 'Help' menu and select 'About' - the version number should be listed here as a series of...

Hello -

Both MediaLab and DirectRT should be able to record data from a stimulant in the manner that you've thought about constructing and using.

I'm not certain - but I believe MediaLab would...

Updating the study will require that a new version of the study is uploaded. It is recommended that your study is completely ready to administer before uploading it to the online system.

[edited from support email]

Once my experiment is online, what would the process be for updating the study?

As of now you will be able to access all collected data through the 'Online Management' control panel from within either DirectRT or MediaLab. The system will take all collected data stored on the...

[edited from support email]

How will the generated data be accessed?

Yes, you will be able to use your own FTP if desired; however Empirisoft's server will still be used to relay information and maintain the study while it is hosted online. When a subject connects to...

[edited from support email]

Will we be able to use our own FTP to host our experiment? How much space will we have?

Yes. Our 2010 versions of both DirectRT and MediaLab have been designed to be completely backwards compatible; therefore, all of your experiments will be compatible with the online system as long as...

[edited from support email]

Is the online system backwards compatible with my older experiments?

All subjects will be able to join your study from any machine in the world as long as they have both an Internet connection and Windows XP, Windows Vista, or Windows 7 (running on a PC or Intel based...

[edited from support email]

Ok. So what operating systems are compatible with this system?

No. In order to run your experiment the user will need to install our online media player to their machine and launch a file that you send to them through email or a specified web URL.

From here,...

Will my experiments be delivered through a web browser?
