SAGE Digital Gene Expression Displayer (DGED)

What the SAGE DGED Tool Can Do

The SAGE Digital Gene Expression Displayer is a tool that identifies those genes that are expressed at significantly different levels (as defined by the user) in two pools of human libraries, based on SAGE tag analysis. The algorithm takes into account the differences in sample size between Pools A and B, which can be large. The user selects a value for statistical significance (P value) and a value for the difference in the level of expression (F value) between the two pools. The results are based on the sequence odds ratio and measure of significance.

Use the SAGE Digital Gene Expression Displayer

The user has the option of comparing two human SAGE library pools, one human SAGE library pool against a user-defined file, or two user-defined files. User-defined files consist of lines of tab-separated SAGE tags and their frequencies.

Note: SAGE tags are either:         • "short" (10 bp), including "extracted short" (10 bp extracted from 17bp tag) or         • "long" (17 bp).
