Jennifer--did you guys ever happen to find a solution to this issue? I ask because another user reported the exact same problem. FYI, they are using v2010.2 so I'm curious especially to know if you...

A note to users running DirectRT v2010.3:

With the DirectRT 2010.3 version, if you ever use MediaLab to call DirectRT in any of your studies, you might find that MediaLab can't find DirectRT--it...

UPDATE - APRIL 3, 2013 (see parent case 1159)

If you are seeing a blank screen when you first start ANY MediaLab experiment or questionnaire--including any of the samples--this may be the fix..

I'll just throw in too that this is a great thread worth checking out (with regard to IAT data analysis)...

Hi all,

Just in case this hasn't been resolved yet, djjohnson--do you happen to be running DirectRT v2010.3 here? That particular version had trouble being found by other programs (including...

Meels86,

I'm not sure what the file open error could be in reference to. If you would like to discuss how we could maybe improve the quarterly reimaging situation, please feel free to email me...

One other note here Lisa--if DirecRT can not pull off exactly what you want on a given machine, you can often use the log file as a guide to tweak your input file. e.g., when you ask for 1500ms and...

Michael--just an FYI re licensing:

If your department was ever licensed to use DirectRT then you should be OK. We don't have a duration parameter on our licenses! The only limitation is that you...

Commas in file names? Huh.. yes, this could cause all sorts of issues! We'll have to make an allowance for this such that it will not throw off the reading of CSV files. Maybe have MediaLab/DirectRT...

Just an additional note on this--it looks from the error that you may be running DirectRT v2010.2? If you update this machine to v2010.3 or later, it will likely run as it does on v2012 machines....

Yes, there do seem to be different issues going on here! TFK--If I recall correctly, there is only one correct column created for any given trial. Its primary purpose is as a convenience for single...

I'd suggest reinstalling MediaLab if it's not running the samples. This is MediaLab v2012.4 on Windows 7? That should be fine--at the very least to run the samples. Hmm--please let us know if an...

Marguerite,

I think Tim's suggestion would work best if you have a script or other program (or the time to do it manually) that would extract the responses and reformat them in the manner of:

You could also try using a password on a basic instruction item. e.g., by adding the "x" parameter such as (x12345). You could alter the wording by editing message #116 in the message.txt file...

Melissa,

Have you ever used a responses.xls file before? One possible approach would be to use scale response items where the labels would be determined dynamically during the session (e.g.,...

If you are also interested in capturing additional keypresses (beyind the first) with the same stimulus, you could add additional columns in the input file. If you repeatedly add the stim, loc, time...

Hmm. The snag with MediaLab launching DirectRT was a known issue with DirectRT (not with MediaLab) in the later releases of DirectRT v2010 and should be fixed in DirectRT v2012. Can you double check...

Would it suffice to have the three steps you mention occur within the same item? I ask because there is no way to eliminate the temporary blank between items (except for with the repeated components...

MediaLab v2012 does in fact use IE7. If you uninstall IE9 and revert to IE7 on these machines, you could likely turn off the javascript error reporting. That should do it.

You can do this from...

Update: We've recemtly had a second case where some bmps with identical dimsensions had a larger file size. Normally BMP files will have the SAME file size. As with the previous case, a small number...

No iPad apps yet but certainly something we've got in mind. For now tho, yes, PC tablets will generally do the job just fine. I would recommend testing any given model tho before purchasing in mass.

What method of programming do you like to use? Do you know VB? It's nice and quick for text manipulation.

Mmm. Those randomization functions don't have a without replacement option like you get with the use of stim files. That makes me wonder if you colud simply enter the stimuli into stim lists and draw...

Should also note that the non-working image was also bigger in file size (~468kb vs 312kb). No idea why as they do both *appear* to be 24-bit bitmaps of equal size which should produce identical file...

There is something "off" about the file. What editor did you save this in? Just curious because I get different bit counts depending on which program I open it in. I also noticed that it's saved at...

Two quick questions first--whicg version of DirectRT are you running--i.e., 20xx.x.x? And what kind of subject IDs are you using? Does it help if you enter an ID such as 1234? i.e., vs. a very large...

For other users who may have this issue, see newer thread located here:

Can you compare the version releases on the machine that works and the one that doesn't? Are they the same? If they are, can you attach a copy of your csv and style file here?

Do the DirectRT samples run on the laptop?

These machines may have had an earlier version of the Windows Media Player on them when they were working. IS it possible you could uninstall the WMP and install an earlier version such as version 9...

I looked over your files. I'm sorry I wasn't clear on the type of randomization used. Apparently it applies only to random value functions as described in this link--

I believe the "invisible cursor" bug was worked out as of version 2010.3. Apologies for the inconvenience! I also think that the conflicting codes issue was worked out as well in 2010.3.

Becky--since it works fine on your desktop can you check two things? 1. That the version of DirectRT on your laptops match the version on your desktop, and 2. That the version of the Windows Media...

I too am able to use the Mangal font in Word, however, Mangal does not show up as a font option when I try to select the editor font.

Are the images that are not appearing always the same ones? If so, could you attach one that works and one that doesn't? Or do all of them sometimes appear, and sometimes not appear?

Take a look at this thread and see if it helps. The gist (of the probable cause) is that in some countries the regional settings need to be set to "USA" or similar in order for the "comma" delimited...

At first, I thought "absolutely nope." Especially with MediaLab. I could imagine ways but given how much randomization you are talking about, these "ways" would be very cumbersome. Especially the...

I've heard of this before. Can you attach a copy of your que file from which the video is called? I'll take a look to see if I notice anything unusual. In the meantime--does it matter if you swap out...

One of the tricky things about this is that media may play perfectly fine in WMP (any version) and yet not look or act the same in MediaLab or DirectRT even though our programs use the same...

Yes, screen orientation hot key sequences can take priority over MediaLab's "secret keys". Most systems will allow you to change or deactivate the "screen flipping" key sequences.

We are working on trying to fix this now. It's a bug of some kind that happens on certain system configurations. Have you had any luck in figuring out a workaround?

DirectRT v2012 generally runs fine on Windows 7. There were a great many changes that occurred in the process of achieving v2012/Windows 7 compatibility. This compatibility is probably the primary...

The downloadable dll's were last used with version 2010. With both DirectRT and MediaLab v2012, we completely have done away with the need for the IP dll's. We just thought it was a pain for people...

Scott,

I'm a bit confused here. With v2012, we have done away with the need for the ip dll's. We hard code the valid IPs into the programs now so that you don't have to do a thing. Just install...
