Allows you to echo input codes to a port of your choice via TTL signals. To do so, create a file called ttlEcho.txt (see example attached below) and place it in your folder along with the main input file. The text file should contain the port address (as a decimal value, not hex), and the time (ms) for which to send the signal.

e.g., Let's say ttlEcho.txt is present and contains:

888,10

Now let's say that the subject presses the space bar (code = 57) on a trial where that's a valid response. DirectRT will immediately send "57" to port 888 for 10ms.

Enhanced voice recording functionality will now allow for manual recording times. This will allow a subject to press a key when they are done speaking to end the recording. To use the new feature, simply add a valid keycode to a fixed length audio RT. e.g.,

rt:57,aud,rec,5000

In this example, DirectRT will record for up to 5000ms or the point at which the subject (or experimenter) hits the spacebar--whichever comes first. This will only work with fixed length audio RTs. See example stroop manual.csv attached below which can be placed in the voice RT sample folder:

C:\DirectRT\Samples\5 other features\12 voice responses stroop

Fixed a bug which requires the following set of conditions: When you have multiple RTs on a single trial, and where one RT is not the LAST RT on that trial, and where that RT takes the numeric keys (1,2,3,2,5,6,7,8,9,0) as valid, the keycode will be listed in the LOG file for that response as the actual code + 1. In contrast, the adjacent Name column will show the correct value.

refined code for the ttlEcho function added previously to v2006.2.13 (see above). The function seems more stable now.

[the following is from the support email of a ttlEcho function tester as of v2006.2.18]

I tested it this morning and it appears to work. Yay! Thank you so much for this; you've saved me countless hour of heartache by not having to use the totally crappy presentation software packaged with my EEG system. THANK YOU! I even checked the timing and everything looks accurate up to the millisecond!

Fixed two problems that DirectRT was having with open ended responses. The first one, and I have no idea how this happened, was causing the word "cat" to appear as the default response for open ended items. the second was that the code 223 was sometimes being stored as the content of the text response. As far as I can tell, these issues were active from August 8th, 2006, affecting v2006.2.16 to v2006.2.18. Both issues are fixed as of v2006.2.19 (patch is attached below for those with an existing v2006 installation).
