## NAME

nad - download genome files from NCBI by accession

## SYNOPSIS

**nad** \[-h\] \[-m {nucleotide,protein}\] \[-e {none,loads,all}\]

## DESCRIPTION

Script to download sequences from GenBank/RefSeq by accession through the NCBI ENTREZ API.

## OPTIONS

\[-F {fasta,genbank,featuretable,gff3}\] \[-o OUT\] \[-p PREFIX\] \[-r\] \[--url\] \[-v\] NCBI-accession \[NCBI-accession ...\]

### positional arguments:

-

  NCBI-accession

### optional arguments:

- **-h**, **--help**

  show this help message and exit

- **-m** {nucleotide,protein}, **--molecule** {nucleotide,protein}

  Molecule type to download. Default: nucleotide

- **-e** {none,loads,all}, **--extended-validation** {none,loads,all}

  Perform extended validation. Possible options are 'none' to skip validation, 'loads' to check if the sequence file loads in Biopython, or 'all' to run all checks. Default: none

- **-F** {fasta,genbank,featuretable,gff3}, **--format** {fasta,genbank,featuretable,gff3}

  File format to download nucleotide sequences in. Default: genbank

- **-o** OUT, **--out** OUT

  Single filename to use for the combined output.

- **-p** PREFIX, **--prefix** PREFIX

  Filename prefix to use for output files instead of using the NCBI ID.

- **-r**, **--recursive**
