Hands-on Analysis of public microarray datasets
"Date: October, 17 2014, from 9h30 to 17h00"
[ Main_Page ]
This basic training will give you an overview of the what GEO has to offer. Several experiments will be analyzed using simple tools to obtain differential gene lists. An introduction to downstream tools dedicated to functional enrichment will close the session.
This training is meant for biologists with little or no data of their own that need to identify genes of interest associated to a given biological problem. The participants do not need any prior knowledge of programing.
- Find relevant data on GEO
- Analyze using the NCBI GEO2R utility
- Continue the GEO2R analysis in RStudio (intro)
- Find cluster using the NCBI GEO DataSets browser
- Analyze the same data using RobiNA
- Perform functional enrichment on the DE gene-lists using public tools
- Users with access to CLC Main can follow the CLC tutorial (VIB-only)
- Users search GEO datasets and analyze them with help from the trainer
You will find in this section exercises performed during the hand-on session.
- PubMA_Exercise.1 Search GEO to find public datasets related to one's project
- PubMA_Exercise.2 Compute differential analysis using GEO2R within the NCBI web-portal (and follow-up in RStudio)
- PubMA_Exercise.2b Optional follow-up analysis demo in RStudio
- PubMA_Exercise.3 Clustering using the GEO Dataset browser (only for data with attached GDS ID)
- PubMA_Exercise.4 Full RobiNA analysis as a standalone desktop alternative to GEO2R and Bioconductor
- PubMA_Exercise.5 Web-tools for functional enrichment of the obtained lists to identify key biological functions
- Analyze_GEO_data_with_the_Affymetrix_software Optional exercise using the Affymetrix Transcription Analysis Console (Windows only free program)
- Normalize CEL files with RMAExpress (Windows and MacOSX)
- PubMA_Exercise.6 Optional exercise using the fully integrated CLC Main workbench (for VIB users and CLC license owners)
- PubMA_Exercise.7 Optional IPA analysis of the GEO2R DE table (for VIB users and IPA license owners)
- Find Transcriptome Signatures with TranscriptomeBrowser Alt option to get enrichment from the GEO data (and much more)
- Analyze your own microarray data in R/Bioconductor See how to analyze your own microarray data in R/Bioconductor

Meta Analysis Resources
- InsilicoDB  offers similar services by linking the data to the Broad data-mining tools GenePattern & Gene-E. Please refer to the InsilicoDB tutorial pages for more info.
Commercial resources licensed by VIB
- Genevestigator not covered during this training but strongly advised for all users who do not have their own MA data but need to find biomarkers.
- CLC Main workbench (http://data.bits.vib.be/pub/trainingen/CLCMain/TutorialMicroarrays.pdf) used in the optional PubMA_Exercise.6
- Ingenuity Pathway Analysis (IPA) is strongly advised for more advanced users/usage. You can use IPA on any Java-installed computer after asking for a personal account to mailto:firstname.lastname@example.org and login in here . Please keep in mind that IPA is only meant for human/mouse/rat data.
