Version 0.7.0 of the openModeller library released

Version 0.7.0 of the openModeller library is now available. This release contains the following main changes/features:
  • New algorithm using Artificial Neural Networks;
  • New option to generate distribution maps directly in ARC/Info ASCII grid format (byte or floating point);
  • New keywords "Spatially unique" and "Environmentally unique" can be used to filter input points when using om_console;
  • Change in AUC calculation: when no absences are provided, instead of using 1-specificity after generating pseudo-absences, it now uses the proportion of points predicted present for a large number of random background points;
  • New method in the RocCurve class to calculate partial area ratio;
  • New parameters to om_test: --calc-matrix, --calc-roc, --num-background and --max-omission.

Please note that the previous release (0.6.1) also includes these changes:
  • Many adjustments in the command line tools;
  • New method in the modelling service to perform external tests;
  • Possibility for the modelling server to submit jobs to Cluster nodes via Condor.
