Enter one or more queries in the text box or use the browse button to upload a file from your local disk. The file may contain a single sequence or a list of sequences. The data must be in FASTA format.
The file should be a plain-text FASTA (.fasta, .fna, .fa) file. In other words, it cannot have formatting as is the case with MS Word (.doc, .docx) or Rich Text Format (.rtf). It cannot be greater than 2MB in size. Do not forget to press the Upload button before submitting your BLAST search.
