1. Specify the input sequences
All the input sequences must be in one-letter amino acid
code. The allowed alphabet (not case sensitive) is as follows:
A C D E F G H I K L M N P Q R S T V W Y and X (unknown)
All the alphabetic symbols not in the allowed alphabet
will be converted to X before processing. All the non-alphabetic
symbols, including white space and digits, will be ignored.
The sequences can be input in the following two ways:
Paste a single sequence (just the amino acids) or a number of sequences in
format into the upper window of the main server page.
Select a FASTA
file on your local disk, either by typing the file name into the lower window
or by browsing the disk.
Both ways can be employed at the same time: all the specified sequences will
be processed. However, there may be not more than 2,000 sequences and
200,000 amino acids in toto in one submission. The sequences
may not be longer than 6,000 amino acids.
2. Customize your run
- Organism group:
Eukaryotes, Gram-negative bacteria or Gram-positive bacteria.
Neural networks, hidden Markov models or both.
- Graphics output:
No graphics, in line GIF or in line GIF and
EPS as links. Click here for examples.
- Text output:
Standard, full or short output format. Click here
- Sequence truncation:
Signal peptides occurr at the N-terminal end of protein sequences;
they are seldom longer than 45 amino acids. It is normally not meaningful
to submit more than 60-70 amino acids per sequence. Therefore, the default
truncation has been set to 70.
3. Submit the job
Click on the "Submit"
button. The status of your job (either 'queued'
or 'running') will be displayed and constantly updated until it terminates and
the server output appears in the browser window.
At any time during the wait you may enter your e-mail address and simply leave
the window. Your job will continue; you will be notified by e-mail when it has
terminated. The e-mail message will contain the URL under which the results are
stored; they will remain on the server for 24 hours for you to collect them.
