Turn Time Audit on For Everything

[kyleheid...@u.northwestern.edu]

Hi
I'm new to e-basic, so I don't know if this is possible, but is there some way to write an inline file that will turn Time Audit on for everything (I'm doing an fMRI study, so it's very important to track all the timing information).

I looked through the generate code and found what appears to be the code that turns on time audit for an individual object (in this case a TextDisplay called PreBlockInstructions)

PreBlockInstructions.Run

      c.SetAttrib PreBlockInstructions.Name & ebDot & ebLogNameOnsetDelay, PreBlockInstructions.OnsetDelay

      c.SetAttrib PreBlockInstructions.Name & ebDot & ebLogNameOnsetTime, PreBlockInstructions.OnsetTime

      c.SetAttrib PreBlockInstructions.Name & ebDot & ebLogNameDurationError, PreBlockInstructions.DurationError

      c.SetAttrib PreBlockInstructions.Name & ebDot & ebLogNameOnsetToOnsetTime, PreBlockInstructions.OnsetToOnsetTime


I would like to make an inline that iterates over every declared variable of the TextDisplay type and call code similar to the above on each of those TextDisplays.

Is this possible/feasible?

Well, if you are really determined, then you might use
Rte.GetObject() to iterate through all the E-Objects and do as you
like (see that topic in the E-Basic Help facility).

But this seems a very peculiar request. Ordinarily, you would take
care of this in E-Studio from the Property Pages of each object of
interest -- either go to the Duration/Input tab and select the
desired Data Logging, or for finer granularity go to the Logging tab
and select whatever you like.

In addition to David's advise, I would also suggest adding a few lines of E-Basic script to calculate stimulus (and response) onset times that are relative to the start of the start of the MRI scanner. These values can then be added to the output file using the c.SetAttrib method. This is a very easy to do and it will save a lot of post processing. (I've seen people creating lots of excel sheets just to get onset times for SPM or FSL. Very time consuming and error-prone.)

Just follow these steps:

1) Declare a global variable to store the scanner start time (i.e. onset time of first EPI scan). This time is normally determined by handling the trigger onset pulse as input response. The global variable should be of type Long (integer) and should be placed in the global user script section:

   Dim ScannerOnset as Long

2) Then copy the trigger onset time to the global declared variable by adding the following after the object that handles the scanner trigger:

   ScannerOnset = WaitForScanner.RTTime

(replace WaitForScanner with the name the actual object)

Also make sure the RTTime attribute itself is logged properly to be able to verify timing.

3) Add a few lines of script at the end of the trial procedure to save the relative times to the log output:

   c.SetAttrib "RelStimOnset", CStr(Stim.OnsetTime - ScannerOnset)

(replace Stim with the name of the stimulus object)
Also make sure the onset attribute itself is logged properly to be able to verify timing.

Repeat 3) for all relevant onset and response times.

that's it
