"A sequence database must be selected" error in search MS2 Data page oo254  2015-11-07 04:01

Hi,

I clicked on search to carry out X!TANDEM PEPTIDE SEARCH, but got the following error message: "A sequence database must be selected". I checked the Protein databse section of this page and only found <root> dropdown link and a "none found" message.

I noticed in the file section that there is no file in the "databases" folder even though I had already downloaded and imported the swissprot database as recommended in the documentation.

Labkey version: apache-tomcat 7.0.62; Database Product Version: 9.4.4

Web browser: firefox

OS: Windows7

I wonder why the protein database is not where it should be.

Hello,

While you can import the FASTA file into the LabKey Server database prior to actually performing searches, you'll need the FASTA file itself too since that's what XTandem will be using. The default location the server uses is a "databases" directory that's underneath your file root.

For more information, see the "Set the FASTA Root for Searching Proteomics Data" section here:

Thanks,
