A Proof-of-Concept FFT Framework for Scalable MRD Follow-updocx Solomon Tessega, MD This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-7803408/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract Single-cell RNA sequencing (scRNA-seq) enables high-resolution profiling of cellular heterogeneity, yet its high dimensionality and sparsity remain major challenges for downstream analysis and visualization. This study introduces a framework that applies the Fast Fourier Transform (FFT) to scRNA-seq expression profiles, converting gene-level signals into frequency-domain representations. By selectively retaining low-frequency components, the method reduces dimensionality while preserving biologically meaningful structure and suppressing technical noise. The approach facilitates clustering, visualization, and annotation tasks. Applied to the PBMC10k dataset, FFT-based compression achieved performance comparable to conventional methods while offering modularity, transparency, and computational efficiency. This framework provides an interpretable and biologically grounded preprocessing strategy for scalable single-cell analysis across transcriptomic and other omics modalities Pathology Bioinformatics Single-cell RNA sequencing (scRNA-seq) Fast Fourier Transform (FFT) Spectral compression Minimal residual disease (MRD) Cell type annotation Full Text Additional Declarations The authors declare no competing interests.
