The latest release can be installed with

$ pip install gencube

Alternative

$ conda install -c bioconda gencube

Email and NCBI API key for E-utilities

When you first run gencube, you'll be prompted for your email and NCBI API key, which are saved in the .gencube_entrez_info file in your home directory for future use. To update these details, edit this file.

All gencube subcommands use E-utilities, requiring an email. Without an API key, you can make 3 requests per second; with an API key, this limit increases to 10 requests per second. If you hit usage limits, provide an API key.

The positional arguments and options shared among the genome, geneset, sequence, annotation, and crossgenome subcommand

When using the above five subcommands, it's important to find genome assemblies required for personal research. Below are the positional arguments and options shared by the these subcommands to browse and search for specific genome assemblies.

positional arguments:
  keywords              Taxonomic names to search for genomes
                        You can provide various forms such as species names or accession numbers
                        Examples: homo_sapiens, human, GCF_000001405.40, GCA_000001405.29, GRCh38, hg38
                        
                        Multiple names can be combined and will be merged in the search results
                        To specify multiple names, separate them with spaces

options:
  -h, --help            show this help message and exit
  -v level, --level level
                        Specify the genome assembly level (default: complete,chromosome)
                        complete   : Fully assembled genomes
                        chromosome : Assembled at the chromosome level
                        scaffold   : Assembled into scaffolds, but not to the chromosome level
                        contig     : Contiguous sequences without gaps
                        
  -r, --refseq          Show genomes that have RefSeq accession (GCF_* format)

genome: Search, download, and modify chromosome labels for genome assemblies

You can download genome data in FASTA format from four different databases (GenBank, RefSeq, GenArk, Ensembl Rapid Release). Each database uses a different soft-masking method, and you can selectively download the data as needed. You can also download unmasked and hard-masked genomes from the Ensembl Rapid Release database.
