VisualData

VisualData is a full software platform for the visualization and clustering of multivariate data sets. VisualData includes all the functionality of VisiSOM and VisiSammon, and has additional features that are designed especially for handling large data sets.

Key features

• 3D Self-Organizing Map
  Visualize change in 3rd dimension. This allows you to assess diversity of cells in a natural way and improve your ability to create diverse sub-sets and clusters.
• Cluster Export Tool
  Save clusters to a data file and analyze these clusters using external applications. This is useful for subjecting clusters to statistical analysis and for creating diverse subsets.
• Analyze time-dependent data
  Trajectories allow you to find correlations in time and behavior. This is especially useful for analyzing cell or bacterial growth patterns.
• Export Cell Data
  Save data of cells into individual data files, which can be used as subsets and they can be analyzed further.
• Email support
  You can find answers to frequently asked questions that other users have had. However, if you do not find an answer to your problem you can email it to our experts and they will help you.
• Sammon´s Map
  Find large patterns and clusters of similar groups. While Self-Organizing Map organizes similar data items together, Sammon´s Map allows you to estimate and compare the similarities of these groups. This in turn allows you to associate cells to super groups that represent some larger behavior or pattern.
• Self-Organizing Map (SOM)
  Explore complex multi-dimensional data graphically and find patterns within the data.
• Subgraphs
  Summarize groups of similar items with bar graphs and line diagrams to quickly familiarize yourself with the data.
• Preprocessing
  Compare distinct variables independently of scale and magnitude by the application of variance based equalization, binarization of strings and replacement of missing values.
