Getting Started
Obtaining and installing geWorkbench. Requirements.
Overview
A brief introduction to the use of geWorkbench.
Loading and Saving Data
Loading microarray data files, merging into one dataset, and saving.
Data Subsets
Subsets of both markers and arrays can be defined for targeted analysis.
Viewing a Microarray Dataset
Survey of geWorkbench visusaliztion tools for microarray data.
Filtering and Normalizing
geWorkbench provides numerous methods for filtering and normalizing microarray data.
Differential Expression
Several variants of the t-test are available.
Clustering
Data can be clustered using a fast hierarchical clustering routine, as well as SOMs.
Marker Annotations
Marker annotations can be retrieved, including BioCarta pathway diagrams.
Sequence Retrieval
Genomic sequences for markers can be retrieved for further analysis.
Pattern Discovery
Upstream seqeunce can be analyzed for conserved sequence patterns.
Promoter Analysis
Search a set of sequences against a promoter database.
Reverse Engineering
Microarray datasets can be analyzed for interactions between markers.
GO Term Enrichment
Determine if particluar Gene Ontology terms are overrepresented in a data subset.
BLAST
geWorkbench can run BLAST jobs on the JCSB cluster.
Synteny
Compare genomic sequence from two different species.
(NOTE: This section of our web site is under active development. More tutorials are forthcoming, covering many usage scenarios for geWorkbench.)
