Learn how to use BLAST as an experimental tool. We will cover the use of filters as BLAST tools and

contrast them with the use of PHI‐BLAST. We will learn about substitution matrices and how the PSSM

relates to PSI‐BLAST. The Gene Expression Omnibus (GEO) is a public repository that archives and freely

distributes microarray, next‐generation sequencing, and other forms of high‐throughput functional

genomic data. Learn how to navigate the GEO interface to retrieve data to inform your experiments.

This workshop will acquaint attendees with NCBI blast tool for comparing nucleotide or protein

sequences to sequence databases and calculates the statistical significance of matches. Attendees will

also learn how to query and download experiments that are MIAME‐compliant.
