It was really helpful. Complete NCBI SNP release VCF files can be found on the SNP FTP site. Please refer to the NCBI genomes FTP site or the NCBI Datasets page to obtain NCBI full genome annotation data. Please contact us if you would like to download a track or track format that we do not currently offer in this dialog. Please refer to the GFF3 file format description. This format is currently only available for gene annotation tracks. When the "Include RNA and CDS features" box is checked, RNAs, CDS, exons, and other features if any annotated on the gene track will be included in the downloaded file.

When this box in unchecked, only the gene feature rows will be included in the file. If the requested range starts or stop in the middle of a feature, the reported start or stop coordinates will match the requested coordinate s. The range will not be extended to encompass the full range of the feature. The CSV format is currently only available for gene annotation tracks. The start and stop coordinates in the table correspond to the full range of the gene feature and may extend past the requested range coordinates. Gene names may not be available for some gene features. The BED file reports six columns accession, start, stop, gene or feature name, score, strand. Currently, the "Include RNA and CDS features" option is not supported for the CSV and BED file format options.

Therefore, these file formats cannot be generated for tracks that only include RNA and CDS features, e. CCDS Features tracks. NCBI SNP tracks and uploaded or streamed variation VCF tracks can be downloaded in VCF format.

I'll be grateful if someone can help me. Thank you. As you have several sequences to download, I think it will be quite easy to add this command into a little bash script to process all of them. The best way to download FASTA sequences for an entire genome is to search for the genome, for example Theobroma cacao genome in the NCBI Assembly portal and use the big blue Download button.

For this, you can use Entrez Direct as mentioned by dc Why not always use Entrez Direct? While it is fine for a small number of sequences, it can be slow to download a large number of sequences. Entrez Direct by default will download uncompressed data so you will end up spending more time downloading a larger file instead of downloading a smaller, compressed file from FTP more quickly. If you were to use Entrez Direct for this purpose, I'd not bother with a bash script and use epost to first post the entire list of accessions and then pipe it to efetch as shown below:. You can also get this link directly, by using Chrome's developer tools F12 , viewing the Network tab, then loading the page in 1. Sorry, I can't post a comment with my reputation score. vkkodali, interesting command I did not know about it ;. However, your command is downloading all sequences from the input file into a single fasta file. I believe that if you have a big bunch of sequences, it could be a little bit tricky after to manipulate that kind of file.

Whether you want a large number of files or just one file is, I guess, a personal choice. A multifasta file is fairly standard though. I don't think you can create individual files for each sequence using epost and efetch ; you will have to either use a bash script or postprocess the efetch output using the unix tool split.
