icetea

icetea provides functions for end-to-end analysis of multiple 5'-profiling methods from raw reads to detection of transcription start sites using replicates, and performs differential TSS detection between groups of samples to integrate mRNA cap enrichment information with transcript expression analysis.

Key Features:

• End-to-end 5'-profiling analysis: Processes raw reads through TSS detection for CAGE, RAMPAGE, and MAPCap data.
• Replicate-based TSS detection: Detects transcription start sites using replicate samples.
• Differential TSS detection: Identifies differential transcription start sites between groups of samples.
• Cap enrichment integration: Integrates mRNA cap enrichment information with transcript expression analysis.

Scientific Applications:

• 5'-profiling method analysis: Supports CAGE, RAMPAGE, and MAPCap data analysis workflows.
• Transcription start site mapping: Enables genome-wide identification of TSS positions from cap-enriched sequencing data.
• Differential gene expression at TSS level: Compares transcription start site usage between experimental conditions or sample groups.
