FastRemap

FastRemap remaps genome reads between different reference assemblies to enable efficient cross-reference alignment for comparative genomics and related analyses.

Key Features:

• Speed Optimization: Provides up to a 7.82× peak processing speed increase over CrossMap, with an average 6.47× improvement.
• Memory Efficiency: Uses as little as 61.7% of the peak memory required by CrossMap (average 80.7%), reducing memory footprint for remapping tasks.
• Implementation Language: Implemented in C++ to leverage performance-oriented optimizations for rapid processing.
• Scalability: Optimized to handle large-scale genomic datasets and extensive read collections for cross-assembly remapping.

Scientific Applications:

• Reference-version remapping: Remapping reads between different versions of the same species' genome assembly.
• Cross-species remapping: Remapping reads between closely related species' assemblies for comparative analyses.
• Comparative genomics and evolutionary biology: Enabling alignment and comparison of genomic datasets across varying reference assemblies for comparative genomics and evolutionary studies.

Methodology:

Builds upon CrossMap principles by refining algorithms and leveraging efficient C++ coding practices to improve both processing speed and memory usage.
