rbamtools

rbamtools provides R functions for processing BAM files, enabling reading, writing, subsetting, alignment depth plotting, and accumulative tabulation of splicing events for sequence alignment analyses.

Key Features:

• Read and Write BAM: Functions to read and write BAM files within R for sequence alignment data access and storage.
• Subset Extraction: Extraction of subsets of BAM data for specific genomic regions or datasets.
• Alignment Depth Plotting: Direct plotting of alignment depth from BAM files to assess coverage across genomic regions.
• SAM/BAM Syntax Alignment: Script syntax that follows SAM/BAM format conventions for compatibility with SAM/BAM data structures.
• Accumulative Splicing Tabulation: Fast accumulative tabulation of splicing events across multiple BAM files for aggregation of splicing information.

Scientific Applications:

• Genomic Data Analysis: Reading, writing, and manipulating BAM files to support sequence alignment–based genomic analyses.
• Gene Expression Studies: Tabulation of splicing events to analyze alternative splicing and gene expression patterns.
• Quality Control and Visualization: Alignment depth plotting to evaluate sequencing coverage and support quality-control assessments.

Methodology:

rbamtools operates by interfacing with the samtools C-library and integrates into R to perform read/write/subset operations, alignment depth plotting, and fast accumulative tabulation of splicing events across multiple BAM files.
