How do I import a DNA, RNA or protein sequence from NCBI?
Import from NCBI
Click File → Import → NCBI Sequences to import a file directly from the NCBI databases (https://www.ncbi.nlm.nih.gov/).
Enter a Gene ID, or one or more Accession numbers into the field provided.
Click import to import the specified file/s.
Use the following formats to import records from the GenBank / EMBL / DDBJ database.
Single GenBank Record
Enter an accession number, with or without a version indicator. For example:
DQ115396 or DQ115396.1
Alternatively, specify a Gene ID. For example.
672 or LOC104244181
Multiple GenBank Records
Separate two or more accession numbers with commas. For example:
NM_006178, NM_008740.4
Range of GenBank Records
Separate the first and last records with a dash. For example:
AF027958 - AF027961
Region of a GenBank Record
To import part of a GenBank record, use a colon with or without the REGION indicator, and specify the sequence range. For example:
NC_000072 REGION: 122552252..122565735 or NC_000072: 122552252..122565735
Reverse Complement of a GenBank Record
To obtain the reverse complement of an entire record, follow the accession number with the (COMPLEMENT) operator. For example:
AL589148.1 (COMPLEMENT)
To obtain the reverse complement of a region, specify the sequence range with a COMPLEMENT() operator. For example:
CP002686: COMPLEMENT(2459491..2463965)
The NCBI record will be imported as a SnapGene file.
