Viewing Gene Expression Data

The View Gene Expression page allows you to obtain gene expression intensity values for a gene or gene list from a normalized dataset, or specify a pre-created gene list. The results table displays group-level information for each gene, such as group means and group standard error.

You can view gene expression data from the main menu in two ways: via Microarray Analysis Tools or via Gene List Analysis Tools:

Microarray Analysis Tools

1. Choose Microarray Analysis Tools in the main menu.
2. Click View expression values for a list of genes in a dataset. The Expression Values page displays.

2. Click Analyze a gene list. A page displays the gene lists to which you have access.
3. Click the gene list for which you want to view gene expression data.
4. Click the Expression Values tab. The Expression Values page displays.

5. You can:
• Click the Array Values link to view the individual array values.
• Click the Group Means link to view the group mean values (this is the default view).
• Click Download to save the group means as well as the individual array values. Follow the instructions that display as you open or save the files. These instructions vary depending on your Internet browser (e.g., Internet Explorer, Firefox, Safari).
