Welcome to g:Sorter!

g:Sorter is a tool for gene expression similarity search. For a selected single gene, protein or probe ID, g:Sorter finds a number of most similar coexpressed (correlated) expression profiles in a specified dataset. Most dissimilar reversely expressed (anti-correlated) profiles may also be selected. A large collection of public gene expression datasets from ArrayExpress are available for analysis for a list of organisms.

The result of g:Sorter analysis is one or more sorted lists of microarray probesets. Several lists are retrieved when several probesets correspond to given input. g:Sorter also finds an intersection list that contains the common elements of all retrieved lists. All related lists can be passed on to functional profiling in g:GOSt and g:Cocoa.

For integrated gene co-expression query across many datasets, please visit our MEM tool.

  • Query 1: 50 probesets with most similar expression patterns to BRCA2 (Pearson correlation) in MAQC-II human breast cancer dataset (See also query to g:Cocoa).
  • Query 2: Same as above, but retrieving both correlated and anti-correlated patterns (mirroring expression query).
  • Query 3: Same as above, but but Excel Spreadsheet (XLS) produced as output (output format).
