It is very easy and straightfoward to use the SSPKA server to make the prediction.

1. Fill in the text area with a protein sequence in the FASTA format and select the corresponding species-specific model.

Note: SSPKA runs on a shared server, it doesn't have unlimited resources for large-scale or batch computations. So, please submit less than 5 sequences each time. Contact us if you need large scale computations and we will be very generous to help.
Because we extract functional annotations from the UniProt database, a UniProt ID for the query sequence is required. In cases where there is no available UniProt ID for your sequence, you can replace the ID with "XXXXXX" or any other characters as shown in the example below for sequences that don't have valid UniProt IDs. In that way, functional features and functional annotations extracted from UniProt are ignored and will not be used by the models. Please be aware that the IDs of submitted sequences should not be identical, as this may confound the prediction outputs due to use of the same IDs among different submission jobs.

2. Wait patiently for the prediction result to be returned by our server. Each sequence may take 5 or more minutes.

3. The prediction result will be displayed like this.

If you have any questions, please do not hesitate to contact us.
