The bug facility is available again. Feel free to submit your reports whenever a crash occurs. It accepts errors generated with recent releases only (currently 'devel' snapshots).

SESAME project that gave birth to the Geopsy project lost its web site a few years ago. wanted to maintain the free access to the results of this friendful collaboration experience. The deliverable are now available at

Server physically moved to LGIT, Grenoble, France. Download facility is now available again, with a much higher bandwidth.

January 15, 2010

A new environment is now available to download softwares. Currently, installation process is still under testing and it may not work properly. We are trying to solve those issues as soon as possible. Linux source package is workin fine. Windows package is crashing at startup due to missing libraries. Mac package works only for fresh installations. If you want to upgrade from a previous version, make sure to remove folders /Library/Geopsy, /Library/, /Library/Qt, /Application/Geopsy, and /Application/ .

June 16, 2008

Exactly two years after the first beta release, we are able to provide an improved and stabilized release called '2.0.0'. Snapshot releases are no longer available. From now on, bug fixes will be directly included in the reference release.

August 29, 2007

A new snapshot page has been created. It is still in its early versions. It will contain video clips that can serve as tutorials to discover geopsy and dinver softwares. Video streaming is working with a flash player, and according to the needed bandwidth, this service may evolve in the future. If you want some particular topics to be documented this way feel free to propose it in our forum.

August 13, 2007

A forum has been created to discuss all problems related to software and scientific matters. You are kindly invited to register and to post there rather than sending e-mail directly to the developer's mail address. Forum

Geopsy is now a multi-platform (Linux, Mac OS X and Windows) graphical SeedLink client to access remote recording devices, read more ...

March 30, 2007

Mac OS X release is now distributed as universal binaries, though a little bigger (15 Mb), power pc and intel Mac users will be able to play with Geopsy and Dinver.

March 19, 2007

Snapshots are again available for download, you are kindly encouraged to download them and participate to the debug process. They contain or will soon contain all new features:

  • Automatic bug reporting
  • New release information
  • Geopsy database file format moved to an xml format without a directory as in the past
  • page format (no longer two files .page and .page.bin), which is an xml format encapsulated in a tar.gz format
  • Cut/Copy/Paste implemented in sheets (figue and all sheets embedded in other applications)
  • Support for Miniseed format and seedlink
  • Support for Cityshark flash card
  • 3 component spac
  • Correlations
  • Improved interface for linear fk (active surface wave experiments) and high resolution
  • Wavelet transform for computing H/V
  • fk2disp and spac2disp improved
  • New set of command line tools to compute dispersion, spac or ellipticity curves (replace *_forward), analyze report files,...
  • New interface for setting target dispersion curve, mode guess option improved.
  • Ellipticity peak inversion fully debugged
  • Poisson's ratio profile when defining parameters for a soil structure
  • Arbitrary conditions between parameters, no longer limited to simple conditions (less than or greater than)
  • Dinver plugins to define your own inversion problem
  • Joint inversion framework: dinver will be capable of inverting various objects at the same time (dispersion curves, ellipticity peaks, refraction arrivals,...) using an innovative and objective scheme (not a simple weighting of misfits)

Deep redesigning is under way (e.g. with modifications of geopsy database file format) and no stable snapshot has been available since last June. The next snapshot is forecasted for the beginning of year 2007. gcc 4, the latest release of GNU compiler, is becoming a standard for more and more Linux platforms. Release 2.0.0-beta from last June was generating errors with this new gcc 4, hence it has been corrected without generating a new version. It is available here. Mac and Windows releases are not affected.

August 23, 2006 Deadline for registration to array course is postponed to September 5th.
June 16, 2006

Release 2.0.0-beta is available for download, relatively stable for all platforms Linux, Mac and Windows.

June 14, 2006

Stability under Windows probably reached the same level as under Linux. Furthermore, since snapshot-20060614, releases under windows are distributed as self-expandable archives with a classical MS Windows installation wizard. A stable release for sesarray-2.0.0 is coming soon for all three platforms (Linux, Mac and Windows).

February 8, 2006

The physical location of geopsy server is going to change before the end of February, and its IP address as well. It won't change anything (bookmarks, ...) except that the access to may be interrupted for short times during this period.

First release of sesarray under Qt4 and GNU Public License. This is a first alpha (unstable and for testing purposes only) and uncomplete release, available under Linux, Windows and to Mac OS X (currently under preparation). Your comments are pretty welcome in order to improve the reliability of this open source software.

The bugzilla server is now replaced by FlySpray which is a lighter bug tracking system, and it is running faster on the Pentium 133 MHz used for It is available at the same address: Creating an account is a necessary step to report bugs. Click on "Register as a new user" to create one (see above link). For those who had already created one on bugzilla, it is necessary to create a new one on FlySpray. The reported bugs have all been moved to the new environment.

Porting to Qt4 is under good ways. This portage will allow releases under Windows with the GPL license (end of the year?). qtbtools, qtbguitools, scifigs and figue are fully translated. Geopsy is being processed. Significant rationalizations of the code were brought.

Figue is almost sufficiently debugged for a beta release. It will be released at the same time as geopsy, probably at the end of August (only inside the sesarray group for intensive testing).

Documentation for geopsy is temporarily stopped (documentation of plugins is still missing).

Portage to Qt4 begins...
