ArrayStar is a powerful software tool for analyzing both global gene expression experiments as well as sequence variation data across a group of samples. For gene expression projects, ArrayStar handles data from oligonucleotide microarrays or spotted arrays and offers you statistical tools in conjunction with graphically rich visualizations to isolate gene sets of interest and identify their biological significance. Multi-sample variation comparisons across genomic data utilize SNP data directly from SeqMan NGen, exported from SeqMan Pro, or via a wizard for customized importing. ArrayStar also offers the optional QSeq application, for RNA-Seq, ChIP-Seq, and miRNA analysis. To learn more, see the Features or Resources tabs below.

 

"It has been a pleasure to use ArrayStar. It is incredibly intuitive and allows microarray analysis novices to produce complex analyses quickly and simply."

Lynette Foo, Stanford University

Features

Gene Ontology

  • Identify relationships between genes with particular biological functions. Video See it!
  • Determine the relative importance of genes in specific processes using the numerous statistical comparisons shown in the association tree.
  • Download the gene ontology tree structure from the Gene Ontology Consortium. View its full name, ID and description when you hover over the term.

    •  

    Visualizations

  • Visualize the expression level changes in individual genes over the course of the experiment through the use of line graphs. 
  • Multi-functional scatter plots can be generated to easily select groups of genes for analysis. Selected genes are shown in white.Video See it!
  • Undock and move views out of the main window so that you can have several views displayed on your screen simultaneously. All views are interactive, so that subsets of genes selected in one view will be selected in all other views.

    •  

    Data Analysis

  • After importing data from a variety of formats, select the normalization method to be applied to your data; RMA, PLIER, quantile normalization, or average summarization.
  • Cluster your data using hierarchical clustering or k-means.  By default, hierarchical groups are displayed on the heat map and k-means groups are displayed as line graph thumbnails.Video See it!
  • Compare SNPs across individuals using the SNP Table, Venn diagrams, and advanced filtering tools.
  • Use statistical analysis tools and techniques to assist with your gene selection studies. ArrayStar's filtering capabilities allow users to quickly examine and re-examine data based on different experimental assumptions.

    •  

    Tabular Views

  • View detailed information for every gene as well as any annotations that are available from imported sources, such as gene names and gene ontology.
  • View and compare detailed SNP and indel data between multiple sequence assemblies.
  • The experiment list view allows you to import and manage the data within your project. Categories or groupings of experiments appear as folders.
  • Organize, manage, and print your gene sets from the Gene Set List view.   A list of all genes within each set is also shown in this view.
