  • Various utilities (written in C#, some need version 2.0 of .NET Framework):
    QuerySampler (new) - a utility for sampling cluster or "snake" from .AVS data file
    ScriptSubst - a utility for multiple-user script generation from a script mask (see input example here)... create user script here
     DistanceVisualizer  - a utility for visualization of data/query regions in 2D space using various (non)metric distances
    PolygonGenerator - a utility for generating synthetic set of polygons
    GenBankExtractor - a utility converting GenBank data from FASTA format into an internal format
    ImageFeatureExtractor - a utility for extracting gray shade histograms from images
    UserImageClassifier - a utility for user-defined assesment of similarity scores for pairs of images
    ImageToVectorTraining - a utility that merges similarity assesments with the feature vectors and prepares an input for training the COSIMIR network
