`gget` is a free, open-source command-line tool and Python package that enables efficient querying of genomic databases. `gget` consists of a collection of separate but interoperable modules, each designed to facilitate one type of database querying in a single line of code. `gget` was developed by [Laura Luebbert](https://github.com/lauraluebbert) in the [Pachter Lab](https://pachterlab.github.io/).
`gget` is part of the [scverse®](https://scverse.org) project and is fiscally sponsored by [NumFOCUS](https://numfocus.org/). If you like `gget` and want to **support our mission**, please consider making a tax-deductible **[donation](https://opencollective.com/scverse/projects/scverse-gget/donate?interval=oneTime&amount=20&contributeAs=me)**.

# 🪄 Quick start guide
Command line:
```bash
# Fetch all Homo sapiens reference and annotation FTPs from the latest Ensembl release
$ gget ref homo_sapiens
# Get Ensembl IDs of human genes with "ace2" or "angiotensin converting enzyme 2" in their name/description
$ gget search -s homo_sapiens 'ace2' 'angiotensin converting enzyme 2'
# Look up gene ENSG00000130234 (ACE2) and its transcript ENST00000252519
$ gget info ENSG00000130234 ENST00000252519
# Fetch the amino acid sequence of the canonical transcript of gene ENSG00000130234
$ gget seq --translate ENSG00000130234
# Quickly find the genomic location of (the start of) that amino acid sequence
$ gget blat MSSSSWLLLSLVAVTAAQSTIEEQAKTFLDKFNHEAEDLFYQSSLAS
# BLAST (the start of) that amino acid sequence
$ gget blast MSSSSWLLLSLVAVTAAQSTIEEQAKTFLDKFNHEAEDLFYQSSLAS
# Align multiple nucleotide or amino acid sequences against each other (also accepts path to FASTA file)
$ gget muscle MSSSSWLLLSLVAVTAAQSTIEEQAKTFLDKFNHEAEDLFYQSSLAS MSSSSWLLLSLVEVTAAQSTIEQQAKTFLDKFHEAEDLFYQSLLAS
# Align one or more amino acid sequences against a reference (containing one or more sequences) (local BLAST) (also accepts paths to FASTA files)
$ gget diamond MSSSSWLLLSLVAVTAAQSTIEEQAKTFLDKFNHEAEDLFYQSSLAS -ref MSSSSWLLLSLVEVTAAQSTIEQQAKTFLDKFHEAEDLFYQSLLAS
# Use Enrichr for an ontology analysis of a list of genes
$ gget enrichr -db ontology ACE2 AGT AGTR1 ACE AGTRAP AGTR2 ACE3P
# Get the human tissue expression of gene ACE2
$ gget archs4 -w tissue ACE2
# Get the protein structure (in PDB format) of ACE2 as stored in the Protein Data Bank (PDB ID returned by gget info)
$ gget pdb 1R42 -o 1R42.pdb
# Download virus genome datasets from NCBI Virus (e.g., Zika virus sequences)
$ gget virus "Zika virus" --host "Homo sapiens" --nuc_completeness complete
# Find Eukaryotic Linear Motifs (ELMs) in a protein sequence
$ gget setup elm # setup only needs to be run once
$ gget elm -o results MSSSSWLLLSLVAVTAAQSTIEEQAKTFLDKFNHEAEDLFYQSSLAS
# Fetch a scRNAseq count matrix (AnnData format) based on specified gene(s), tissue(s), and cell type(s) (default species: human)
$ gget setup cellxgene # setup only needs to be run once
$ gget cellxgene --gene ACE2 SLC5A1 --tissue lung --cell_type 'mucus secreting cell' -o example_adata.h5ad
```
