Microarray Data

The Data Set

The website offers three types of searches to allow a user to: (1) limit the visualization to a subset of probes (or genes) of interest (Gene Search); (2) use a 'seed' gene to find other genes with similar expression patterns (Find Correlates); and (3) compare expression between different anatomic regions (Differential Search).

Gene Search

To search for a gene category by disease, pathway, cell type or function, click on the relevant search term in the tag cloud. To search for probes associated with a specific gene or group of genes, select the Gene Search radio button and type the gene name, gene symbol or Entrez Gene ID in the search box (multiple genes searches require an OR between gene names) before clicking the Search button.

Boolean Syntax

The following special operators can be used to build queries:

• AND, OR and NOT may be used in place of their corresponding operators. They must be upper case.
• The AND operator (&) is implicit, so spaces between words that are not separated by an operator will be treated like an &.
• OR (|) has higher operator precedence than AND (&).
• Parenthesis can be used to group criteria, but nested parenthesis are not supported at this time.
• The NOT operator (!)is not supported within parenthesis.
