Introduction

This is the folder which contains all AltAnalyze relationship files used to:

• perform microarray normalization (library files, APT)
• Annotate gene expression results
• Identify which probesets align to which exons and annotations
• Associate proteins, domains and motifs with probesets
• Determine reciprocal junctions to compare for junction arrays

Nearly all AltAnalyze annotations are pre-built as opposed to extracted directly from array manufacturer files (Affymetrix CSV files). Files are downloaded from the main menu by selecting a species to analyze.

Details

Most users will not need to ever open this directory unless they need to do the following:

• Look up array annotations in batch (e.g., AltDatabase/EnsMart55/Hs/exon/Hs_Ensembl_probesets.text).
• Customize database files (developers and advanced users only)
• Copy Affymetrix library and annotation files for other purposes

Multiple database versions will be stored in this directory for different versions of Ensembl (e.g., Ensembl version 55 - EnsMart55).
