architectural-analysis
by pedronauck
Deep architectural audit focused on finding dead code, duplicated functionality, architectural anti-patterns, type confusion, and code smells. Use when user asks for architectural analysis, find dead code, identify duplication, or assess codebase health.
clinpgx-database
by jaechang-hits
"Query PharmGKB (Clinical Pharmacogenomics) database via REST API for drug-gene interactions, clinical annotations, dosing guidelines (CPIC, DPWG), variant-drug associations, and pharmacogenomic pathways. Search by gene, drug, rsID, or pathway. No authentication required. For somatic cancer pharmacogenomics use cosmic-database or opentargets-database; for drug structures use chembl-database-bioactivity."
bioservices-multi-database
by jaechang-hits
Unified Python interface to 40+ bioinformatics web services via bioservices library. Query UniProt proteins, KEGG pathways, ChEMBL/ChEBI/PubChem compounds, run BLAST searches, map identifiers across databases, retrieve GO annotations, and find protein-protein interactions. For single-database deep queries use dedicated tools (gget for Ensembl, pubchempy for PubChem); bioservices excels at cross-database integration workflows.
nnunet-segmentation
by jaechang-hits
"Train and deploy automated medical image segmentation models using nnU-Net's self-configuring framework that auto-selects optimal architecture, preprocessing, and training for any modality. Supports CT, MRI, microscopy, and ultrasound with 2D, 3D full-res, 3D low-res, and cascade configurations. Pipeline: convert dataset → plan and preprocess → train (5-fold cross-validation) → find best configuration → predict → ensemble. Use when classical segmentation fails and annotated training data is available."
ena-database
by jaechang-hits
"European Nucleotide Archive (ENA) REST API access for genomic sequences, raw reads, assemblies, and annotations. Portal API search with query syntax, Browser API retrieval (XML/FASTA/EMBL), file reports for FASTQ/BAM download URLs, taxonomy queries, cross-references. For multi-database Python queries prefer bioservices; for NCBI-specific queries use pubmed-database or Biopython Entrez."
featurecounts-rna-counting
by jaechang-hits
"Counts aligned RNA-seq reads overlapping gene features in a GTF annotation. Takes sorted BAM files from STAR alignment and a GTF file; outputs a tab-delimited count matrix per gene across all samples. Handles strandedness (0=unstranded, 1=stranded, 2=reverse-stranded), paired-end, and multi-sample batch counting in a single command. Use Salmon instead for alignment-free quantification; use featureCounts when STAR BAMs already exist and a gene-level count matrix is needed."
cellxgene-census
by jaechang-hits
"Query CELLxGENE Census (61M+ cells) programmatically. Search by cell type, tissue, disease, organism. Get expression matrices as AnnData, stream large queries out-of-core, train PyTorch models on single-cell data. For analyzing your own data use scanpy; for annotated data manipulation use anndata."
ensembl-database
by jaechang-hits
"Query Ensembl REST API for gene/transcript/variant annotations across 300+ species. Retrieve gene info by symbol/ID, sequence, cross-references (HGNC, RefSeq, UniProt), variants, regulatory features, comparative genomics. For bulk local access use pyensembl; for pathway lookups use kegg-database or reactome-database."
bedtools-genomic-intervals
by jaechang-hits
"Toolkit for genomic interval operations on BED, BAM, GFF, VCF files. Find overlapping regions, merge adjacent intervals, calculate coverage depth, extract FASTA sequences, find nearest features, and manipulate interval coordinates. Essential for ChIP-seq peak annotation, target region filtering, and genome arithmetic. Use tabix instead for indexed single-region queries; use deeptools for normalized bigWig coverage."
