UniProt TrEMBL database

Question

[Danit]

Hi, I downloaded the TrEMBL from the UniPort web, among the 3 options (xml, fasta, text) I chose fasta format. I got the following format "uniport_trembl.fasta.gz". when I open it to extract the files, at some point an error appears - "an error occurred while extracting files". How can I solve this problem? I need to use this database as a query with my own dataset.

Thanks

You have to uncompress the file using gunzip uniport_trembl.fasta.gz before you can open it. This is going to be a simple multi-fasta format sequence file and not a database.

If you are looking to do sequence similarity searches then you will need to create an index (e.g. with blast+) and then do the search with your query.
