Just plain sequence alphabets in either lower or upper cases. Spaces, tabs, blank lines and digits are allowed and ignored. Characters other than sequence letters may cause problems in most cases. In this format, only one sequence can be submitted in a single input field.
The same as plain text format except a sequence may begin with a header line that has '>' as the first non-blank character. The first word following '>' will be used by some programs as the label to identify the sequence in their outputs. Note that the header line must be a line by itself (starting the sequence on a new line). Some programs need a list of oligos. The oligos must also be in the fasta format. Some programs allow or request more than one sequence in a single input field. In such cases, the header line is required for each sequence. Without the separating header lines, a program would not be able to tell sequences from one another. Here is an example of fasta format.
This format is the format of a GenBank entry. Each input can include multiple entries. Here is an example of a GenBank entry.
The same as for DNA sequences.
