A package for downloading and analysing data from the GCP archives has
been created by William Treurniet. It is called EggAnalysis and can be
downloaded from his website at
Here is his description:
I've developed a new application for Windows for analyzing egg data
in the format delivered by the Custom Basket Data Request web page. I
would like to contribute this software (C++ source code and
executable) to the research community.
The program has a remote access capability which enables it to
download data directly without using a web browser. Of course, it can
also read the same data stored locally. And there is a batch mode
which enables it to analyze a number of time intervals without manual
intervention. Further, start and stop times can span a day boundary.
I lifted some code from the EGGSHELL project [created by John Walker]
for some of the
statistical analysis, so it generates the usual stuff to do with the
Stouffer_Z score. I added some more output variables related to the
egg variance, as well as several smoothing filters which can be
applied to the output time series. There is also the option of
generating audio output for several variables where pitch corresponds
to the variables' magnitudes. Also, if Gnuplot is installed, data
plots may be displayed from within the application.
With regard to checking data integrity, the program only
excludes data that falls outside the range of 55-145.
You are welcome to download and use the EggAnalysis tools. We are
interested in comments and suggestions, as well as bug reports.
