Guisdap 9.2

This release of guisdap contains new features and bug fixes, but everything is made compatible with older versions (hopefully). The package should be compatible with not too ancient Matlab versions (>2016), but there may (or may not) be some problems on specific platforms.


Guisdap 9.2 has been succesfully installed on linux, and with somewhat modified procedures also other on platforms. The software is available as a
git repository, or as precompiled packages.
For best performance it’s adviced to compile the git repo files:

cd into the guisdap directory
make a link of bin/guisdap to a place on your path (ex /usr/local/bin)

Provided is a search path to ~/gup/mygup where your personal and edited distribution files should go.


On a unix system prompt, type “guisdap –help” to see all the switches available. Normal analysis is done running “guisdap -a” which will bring up a window with some entries to fill in. (Hopefully self explained) This is the same as “guisdap” and then “analyse”. When finished hit “GO”. A more detailed instruction can be found at here.There is also a course presentation describing how to initialise new experiments and some useful tips on more specialised analysis. The initialisation scripts are available with “guisdap -i”.

For Windows there is a startup script windows_start.m available that should be chosen as ‘Run’ with right-click.

New features

With version 9.2 the new HDF5 format for the result data is introduced.

    • There is a comprehensive document describing the format: share/doc/pdf/EISCAT_Hdf5_data_format.pdf
    • There is a quicklook spreadsheet file for the format: matfiles/Guisdap_Parameters.xlsx
    • More rawdata taking experiments have been prepared for automatic lagprofiling and analysis mainly to get sub-dump resolutions of data
    • The libraries have been rewritten to allow more compilers and be more matlab independent
    • Mex routines are now optional
    • The internal time format is now TAI to allow unique time stamps
    • Numerous bug fixings and updates
