S-GeMS Changelog

What's new in S-GeMS 2.5 Beta

Dec 28, 2011
  • Improvements:
  • Regions:
  • All geostatical algorihtms can be constrained within a sub-space of a grid. This sub-space is defined by a region. The region is well implemented within the algorithms but had not been implemented for the visualization. This feature will be available in the next version (likely January 2012).
  • Python commands:
  • Several python commands had been added to provide better control from python scripts. See here for a list.
  • CSV file format:
  • SGeMS can now load data from comma separated file (csv). The first line containes the names of the variable with the variables in following lines.
  • Alpha numeric field:
  • SGeMS can now load alpha numeric field when imported from a csv file format. There is now a structure called a categorical definition that will provide the mapping between a alpha-numeric field and its corresponding numerical values.
  • Groups:
  • Property can be grouped together for a cleaner display. For instance a set of simulations ort indicators will be inside one group. Python commands had been added to use that functionality.
  • Right clicking actions:
  • Right clicking on a grid, a group or a property name provides some options such as creating indicator data or taking the log of each value within a property.
  • Pyhton plugins:
  • You can have access to user-defined python script when right-clicking on either a property or a group of properties.
  • Quadrant Search:
  • Specification of search strategy for the variogram-based algorithms.
  • Masked Grid:
  • A type of grid that is build by applying a mask on a cartesian grid. The advantage is that if only 50% of the blocks are actually active, the array necessary to store the values will be 50% smaller than the one use for the full grid. This is mostly useful on very large grid. A masked grid could be mimicked by using a cartesian grid with a region defining the mask.
  • 64 bits
  • Eanble the use of very large grids and better performace of the SNESIM algorihtm.
  • Regressions:
  • Volume rendering:
  • The volume rendering is now only possible on NVIDIA video card. This will not be fixed on this version since the next SGeMS release will have a completely new (and improved) visualization features that includes the visualization of the regions.
  • Variogram modeling:
  • The regions had not been implemented in the variogram modeling tool. This part of the software is unchanged hence has fallen behind in this version.
  • Kriging from blocks
  • The algorithms BKRIG, BESIM and BSSIM have been removed, they were too unstable and I do not have the time to maintain them. Contact me if you were interested in these algorithms.
