First off, thanks for all the work in creating, adapting, and modifying this syntax, and posting it for all to use!
That said, I have a question about the syntax you posted (the referenced post is shown below). Because I have a more complex coding scheme than even #ed Ss = order 1 (e.g., white + good first) and odd Ss = order 2, I merged all files from each separate order together rather than merging both orders together. In effect, it is as if I have not counterbalanced order (I have, but I will deal with this in another way) - and thus, in each merged file there is a single order of presentation. Does anyone out there know of an easy fix to the syntax so that SPSS will NOT assume that I have different orders for odd and even #ed Ss when computing the D statistics? I'm not sure what part I need to take out. It seems as if it should be simple, but in fact, the syntax is rather complex in places and I'm not sure what part needs to be changed.
Thanks!

I am sure you will get a lot of replies but if you don't, call me and i will walk you through easily changing the Inquisit syntax to work with Direct RT (all you need to do is transform the variables so they are named the same as in the syntax and check a couple of procedural things in your direct rt program). My cell is *** (I am a post doc of Mahzarin Banaji's).
This all assumes that you programmed and collected data using a 7-block IAT
[LIST=1][*]Merge all of your DirectRT files with the filemerge software that Blair Jarvis (from Empirisoft) that comes included with DirectRT (save the merged file as ".csv" -- it will pull into SPSS much better than .txt).[*]Pull the big huge file into SPSS.[*]In DirectRT, your trial #rs must begin with #1 (and go to whatever). SO: if the range in DirectRT is 5-380, you need to transform it to range from 1-376.[*]In DirectRT, your block numbers need to range from 1-7 (i recall default coding the blocks 0-6 so you will want to transform the numbers to range from 1-7)[*]In DirectRT your errors vs correct responses may have been coded
differently than the syntax needs. Your errors must be coded = 0 and correct responses = 1[*]A critical issue is one of IAT order. the IAT syntax thinks you ran all odd subjects as order #1 (e.g., black+bad & white+good) and all even subjects as order #2 (e.g., black+good & white+bad; see syntax from the IAT SPSS syntax below).[*]In the syntax file, you MUST change the order variable syntax or compute an appropriate "order variable" in your SPSS data file and then remome the part of the syntax that looks like this:
[code]*If order of the combined
tasks differs in some other fashion, provide an appropriate replacement
* for the following line (which works when order differs for odd and even
subject numbers) .
COMPUTE ORDER = mod(subj, 2) .
RECODE ORDER (0=2) .
