Okay; The problem was that I have
ptsbefore = 4
ptsafter = 8
SO I'll add a time point to the template.
One more question:
Does this mean that all the files batches successfully created for individual conditions only have the first 12 TRs of data?
Thanks,
Dharol |

The epoch averages for ptsbefore=4 and ptsafter=8 would have 13
time points. 8 + 1 + 4 (includes the timepoint of the event
itself). The template is only used after creating the averages.

One remaining question:
Why can batches successfully create data files for individual conditions if the template is 12 but ptsbefore/after are 13? Does it just not process the 13th data point?
Thanks so much!

What do you mean by "successful"?
Epoch averages and related data (_avg, _std, _n, etc.) do not require the template, so those data will be successfully generated regardless of the template. The template is only required to create _cor and _tmap files. If the template has the wrong number of timepoints, you shouldn't get any _cor or _tmap files, either for individual conditions or for comparisons. Do you get _cor or _tmap files for individual conditions when the template has the wrong number of timepoints? |

Hi,
I'm new to event_stats and I was wondering if anyone has a script for converting 3-column EV files into the .xml files that event_stats needs. I see there are several other functions for taking standard output from Presentation, Cigal, and E-Prime and generating the .xml files.
Thanks,
David |

We have ways to go from the XML to the 3-column timing files, but no easy way to go directly from the 3-column to XML. I'm guessing you have multiple 3-column timing files, each representing one condition. If you were able to get this data into a tab-separated or comma-separated file that looked something like this:
NAME,START,DURATION,WEIGHT
fixation,0,10,1
face,10,2.5,1
face,15,2.5,1
face,20,2.5,1
ask,25,2.5,1
probe,30,2.5,1
etc.
then you could use eventstable2xml (run it with the --help option to get a help message).
It actually wouldn't be too hard to put together a script that did this automatically, I suppose. I'll see what I can do.

Thanks, Syam. A script would be useful for anyone using PsychToolbox (or something else with non-standard output) for stimulus presentation since the output files aren't in a standard format. The 3 column EV files are, however, standardized for almost everyone.
I'll see if I can convert my 3-column files into the format you suggest.

| A script called "3column2xml" is now available on golgi. Use it with the --help option to get a help message. |
