Tripal MegaSearch

Tripal MegaSearch provides querying and downloading of biological data within the Tripal framework from Chado databases to enable retrieval of gene, germplasm, marker, map, QTL, genotype, phenotype, and expression datasets for genomic analyses.

Key Features:

• Data Querying and Filtering: Supports selection among predefined data types including gene, germplasm, marker, map, QTL, genotype, phenotype, and expression, with gene-specific filters for name, chromosome position, and functional annotations.
• Customizable Data Fields: Allows selection of output fields such as gene name, organism, type, chromosome position, functional annotations (BLAST, KEGG, InterPro, GO term) and sequence export in FASTA format.
• Flexible Data Sources: Operates on Tripal MegaSearch materialized views (MViews) or Chado base tables and supports creation and use of custom MViews.
• Download Management: Enforces administrator-configurable download limits to manage server resources.

Scientific Applications:

• Genomics: Retrieval and export of gene- and genome-associated datasets for comparative and functional genomics analyses.
• Genetic Mapping and QTL Analysis: Selection and export of marker, map, and QTL datasets for linkage and association studies.
• Phenotype and Genotype Analysis: Aggregation of genotype and phenotype data for trait analysis and germplasm characterization.
• Functional Annotation Aggregation: Compilation of annotation sources (BLAST, KEGG, InterPro, GO term) for gene function interpretation.
• Example Deployments: Instances include the Genome Database for Rosaceae and TreeGenes.

Methodology:

Integrates with the Tripal framework and leverages the Chado database schema, using Tripal MegaSearch materialized views (MViews) or Chado base tables with support for custom MViews.
