svdetect_compare_step

svdetect_compare_step compares structural variants between two genomic samples by analyzing anomalously mapped read pairs from paired-end and mate-pair next-generation sequencing data to localize and classify genomic rearrangements.

Key Features:

• SVDetect foundation: Builds on SVDetect capabilities for detecting structural variations from paired-end and mate-pair NGS datasets.
• Input data types: Operates on paired-end and mate-pair reads from platforms including Illumina GA and ABI SOLiD.
• Anomalous read-pair analysis: Leverages anomalously mapped read pairs identified by short-read aligners to localize genomic rearrangements.
• SV classification: Classifies detected events into large insertions-deletions (indels), inversions, duplications, and balanced and unbalanced inter-chromosomal translocations.
• Output formats: Emits predicted structural variants in various file formats suitable for graphical visualization and downstream analysis.
• Workflow integration: Integrates with the Galaxy framework for incorporation into reproducible analysis workflows.

Scientific Applications:

• Comparative genomics: Comparison of structural variant profiles between samples to study genetic diversity and genomic rearrangements.
• Disease-related SV analysis: Identification and classification of SVs relevant to studies of disease mechanisms and genomic pathology.
• Genomic research workflows: Inclusion in data-intensive and reproducible workflows for downstream visualization and interpretation of structural variants.

Methodology:

Analyzes anomalously mapped read pairs from paired-end and mate-pair NGS (Illumina GA, ABI SOLiD) using sliding-window and clustering strategies to localize and classify structural variants and outputs predicted SVs in various file formats.
