Here's a short description of the query language syntax: (courtesy of syam)
QUERY: Would match any event where:
CONDITION The CONDITION is true
(QUERY) The QUERY is true
QUERY1 & QUERY2 Both QUERYs are true
QUERY1 | QUERY2 Either QUERY is true
CONDITION: Would match any event where:
param param is > 0
param(>numval) param is greater than numval
param(<numval) param is greater than numval
param(VALUELIST) param equals any value in VALUELIST
param > numval
param >= numval
param < numval
param <= numval
param == numval_or_strval
param != numval_or_strval
[params can be on the right-hand side of these expressions too]
VALUELIST:
VALRANGE
VALRANGE,VALUELIST
VALRANGE: (e.g. "1,3,4-9,22" or "red,green,orange")
strval
numval
numval1-numval2 equivalent to numval1,numval1+1,...,numval2
Definitions:
param any recognized state variable name
strval a string surrounded by quotes (single or double)
numval a number
Examples:
QUERY DESCRIPTION
shape=='square' Match all events whose 'shape' param is 'square'
onset >= 30
Match all events which happened starting at or after time 30
shape=='square' & onset>=30
Match all 'square' events starting at or after time 30
code==4 & color!='red'
Match all events with code 4 whose color is not red
code(2,4,6-10)
Match events whose code is 2,4,6,7,8,9,or 10
actual_response==2
Match events which have a actual_response (perhaps a
button number) param with value 2
actual_response==correct_response
If your events have both the actual_response and
correct_response encoded as parameters, this will
match only correct responses.

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

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.

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.

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,

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? |

Okay; I specified 13 TRs in ptsbefore and ptsafter, so I'll add a timepoint to the template.
One remaining question:

Thanks so much!

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.

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,

Does it actually run bxh_correlate successfully for some?
bxh_correlate is only run on the individual conditions.
The comparison happens afterwards with bxh_ttest.
What do you specify for ptsbefore and ptsafter?
You have 12 points in your template, so ptsbefore + ptsafter + 1
should equal 12. |

Oh -- It's having a problem when it tries to run tcompare. It says:
Number of time points in data and template must match!
Error running /usr/local/bin/bxh_correlate.
My template is:
--template 0,0,0,0.00022185,0.039984446,0.50459248,0.971434037,0.838679245,0.47536268,0.178599023,0.062807994,0 --
It works for running single conditions, so I'm not sure why it doesn't work for the comparison?
Thanks,
Dharol

Does it give any errors before that? In the _LOG.txt file? |

Sitting down with Dharol, the permissions problems were due to opening the script eventscreate in WordPad on Windows, and when it saved it removed executable permission. To restore executable permission to a file, do:
chmod +x MYSCRIPT
However, that was not the only problem. Editing a golgi script in Wordpad is a bad idea, because it will use Windows line-ending characters which are not supported by shells on golgi. Most UNIX systems have programs called dos2unix and unix2dos that will convert the newline conventions from one to the other, but that did not exist on golgi, so I've provided bare-bones versions that you can use:
dos2unix MYFILE
will "fix" any script you may have accidentally edited using WordPad or other Windows editor.
