clc_mapping_info

clc_mapping_info analyzes read mapping data from Roche 454 pyrosequencing (250–450 base pairs) to report mapping details that support evaluation and interpretation of transcriptome assemblies.

Key Features:

• Read Mapping Analysis: Provides detailed information about how individual sequencing reads align to reference sequences or assembled contigs.
• Integration with Assembly Tools: Complements transcriptome assemblers such as CAP3, MIRA, Newbler, SeqMan, and CLC by reporting mapping quality and coverage metrics for assembled contigs.
• Support for Multiple Assemblers: Accepts and interprets outputs from different assemblers to enable evaluation and comparison of assembly strategies.
• Enhanced Data Interpretation: Supplies mapping-derived metrics to identify issues such as redundant contigs and variable read coverage across assemblies.

Scientific Applications:

• Transcriptome Assembly Optimization: Assesses assembly quality for Roche 454 transcriptome datasets (250–450 bp) to inform selection of assembly parameters and tools.
• Data Integration and Merging: Supports merging assemblies from different programs to improve alignment consistency and contig size uniformity.
• Comparative Analysis: Enables systematic comparison of assembler performance using metrics such as contig length, novelty, and redundancy derived from mappings.
• High-throughput Sequencing Data Management: Facilitates management and interpretation of read mapping and assembly outputs from high-throughput sequencing experiments.

Methodology:

Analyzes read mappings to evaluate contig length and quality, alignments to reference sequences or assembled contigs, and coverage distribution across assembled transcripts.
