freak

freak generates residue and base frequency tables and plots to quantify sequence composition in nucleotide and amino acid sequences.

Key Features:

• Residue/Base Frequency Analysis: Calculates counts and relative frequencies for residues or bases from input biological sequences.
• Table and Plot Generation: Formats frequency data into tabular outputs and graphical plots for downstream analysis.
• EMBOSS Integration: Operates within the EMBOSS suite to interoperate with other EMBOSS applications and third-party software.
• Extensible C-based Implementation: Built on EMBOSS C programming libraries, enabling developer extension and customization.
• Scalability: Designed to handle large sequence datasets efficiently within the EMBOSS environment.

Scientific Applications:

• Sequence Analysis: Supports motif discovery and sequence comparison by providing residue and base frequency profiles.
• Data Visualization: Produces visual representations of sequence composition to aid interpretation and communication of results.

Methodology:

Analyzes input biological sequences to calculate per-residue or per-base frequencies, formats results as tables and graphical plots, and is implemented using EMBOSS C libraries for integration within the EMBOSS suite.
