SAGE Advanced Query

 Help
Back to the simple Query SAGE Data page.

SAGE tag sequences and their expression values can be obtained by querying the SAGE data of Velculescu et al. in any one of three general ways using Query syntax language:

  1. by gene or ORF name
  2. by SAGE tag sequence
  3. by relative expression values

Query submission
  1. Enter the search criteria using the Query syntax language:


    Note: This search is case insensitive. Include the wildcard character (*) to broaden your search.

  2. Sort the results by the chosen value: (Optional)

    Sort 1: Sort 2: Sort 3:
    Descending Ascending Descending Ascending Descending Ascending

Query Syntax Language

  1. Each query is entered in the form of an expression:


    		 Name Comparison Operator Value Example

    		GENE = ACT1 GENE=ACT1

  2. Logical operators are used to combine two or more queries together. Enclose each separate query in parentheses:


    		Query1 Logical Operator Query2 Example

    		(L > S) AND (S < G2M) (L > S) AND (S < G2M)
