HSLS MolBio Workshops

This workshop covers how to search and download gene counts from gene expression studies (RNA-seq / microarray) by searching the Gene Expression Omnibus (GEO) database using Correlation Engine, iDEP R shiny app (RNA-Seq), and Geo2R (Microarray). We also cover how to prepare the data for NCBI GEO database submission.  

Participants will learn how to

• search and download data from GEO (ex: gene counts from an RNASeq study )

• analyze the data using GEO2R and  iDEP R shiny app

• submit the data to NCBI GEO data repository

 

Target Audience

Experimental biologists seeking to analyze gene lists through omics experiments. The software covered in the workshop operates through a user-friendly, point-and-click graphical user interface, so neither programming experience nor familiarity with the command line interface is required.
