We present NeoantigenEngine, a complete neoantigen prediction pipeline implemented entirely in Python using NumPy, SciPy, pandas, and matplotlib — no NetMHCpan, pVACtools, IEDB, or R required. NeoantigenEngine provides five analysis modules: (1) somatic mutation to mutant peptide generation (9-mer and 10-mer sliding windows), (2) MHC-I binding prediction via built-in PSSM matrices for HLA-A*02:01, HLA-A*01:01, and HLA-B*07:02, (3) immunogenicity feature computation (Kyte-Doolittle hydrophobicity, net charge, foreignness, aliphatic index), (4) multi-factor neoantigen prioritization (binding × expression × clonal fraction × immunogenicity), and (5) a 6-panel visualization dashboard.

We present BulkDeconv, a complete bulk RNA-seq cell type deconvolution pipeline implemented entirely in Python using NumPy, SciPy, pandas, and matplotlib — no CIBERSORT, TIMER, EPIC, quanTIseq, or R required. BulkDeconv provides five analysis modules: (1) a built-in LM22-inspired signature matrix covering 22 immune cell types and 50 marker genes, (2) quantile normalization preprocessing, (3) Non-Negative Least Squares (NNLS) deconvolution with fraction normalization, (4) bootstrap confidence intervals (95% CI, n=100 resamples), and (5) per-cell-type quality metrics (Pearson r, Spearman r, RMSE).

We present ImmunRepertoire, a complete immune repertoire analysis pipeline implemented entirely in Python using NumPy, SciPy, pandas, and matplotlib — no TRUST4, MiXCR, VDJtools, immunarch, or R required. ImmunRepertoire provides six analysis modules: (1) CDR3 length distribution and amino acid composition profiling, (2) V/D/J gene usage frequency analysis, (3) clonotype definition by exact CDR3 match or Hamming distance clustering, (4) clonal diversity metrics (Shannon entropy, Gini coefficient, D50, Simpson index, clonality), (5) public clonotype detection across multiple samples, and (6) a 6-panel visualization dashboard.

We present RNAVelocity, a complete RNA velocity analysis engine implemented entirely in Python using NumPy and SciPy — no scVelo, velocyto, loom, or anndata required. RNAVelocity implements four velocity models: (1) steady-state ratio estimation (La Manno et al.

We present EpigenomicsEngine, a complete epigenomics analysis pipeline implemented entirely in Python using NumPy, SciPy, and scikit-learn — no MACS2, HOMER, deepTools, Bowtie2, or R required. EpigenomicsEngine provides five analysis modules: (1) fragment-level peak calling via a Poisson-based local background model, (2) differential accessibility testing with DESeq2-style negative binomial dispersion estimation, (3) de novo motif discovery using position weight matrices and JASPAR-style scoring, (4) transcription factor footprinting via Tn5 insertion bias correction, and (5) chromatin state segmentation using a Hidden Markov Model.

An intelligent experimental log generator that creates structured documentation from experimental protocols. Supports multiple output formats including Markdown, JSON, and structured reports.

A scalable batch file processor designed for large scale bioinformatics workflows. Features include batch renaming with regex, file organization by extension or size, and statistical analysis.

A comprehensive tool for converting between bioinformatics file formats including FASTA, FASTQ, GenBank, PDB, BED, VCF, CSV, and JSON. Supports batch processing and validation.

Search PubMed literature database and extract abstract information. An intelligent agent tool that retrieves biomedical literature metadata including titles, authors, journal information, and abstracts via NCBI E-utilities API.

Annotate genetic mutations with functional impact, pathogenicity predictions, and clinical interpretations

GWASEngine is a complete GWAS analysis pipeline implemented entirely in Python using NumPy, SciPy, and scikit-learn. Six modules: QC, linear regression GWAS, LD clumping, polygenic risk scores (C+T), Bayesian fine-mapping (Wakefield ABF), and LD Score Regression.
