NemaBLAST versus transcript contigs, isotigs & genes:

Please enter your sequence here (must be in FASTA format)

Select all the species you wish to include in your blast database by selecting individually or by clade from the menu below. Also be sure to enter your query sequence in the window above, either manually or fetch the sequence using the GenBank accession number. Next, choose the version of BLAST you want to run, and select whether or not to filter and mask your query. And be sure to enter your email address in the appropriate text box. Then finally press the BLAST Search button and your job will begin.

As of August 1st, 2011, NGS assembly contigs have been added into blast dbs where available. Typically these represent Newbler assemblies of 454 cDNA data. These references have been prefixed with a 4-letter abbreviation followed by an underscore to make them stand out from hits to older EST contigs (ex. Tcir_isotig00001).

As of November 1st, 2012, 10 CDS genesets are available as selectable dbs. These represent CDS for current, final set of genes from the organisms Ascaris suum, Brugia malayi, Bursaphelenchus xylophilus, Caenorhabditis elegans, Homo sapiens, Loa loa, Meloidogyne hapla, Schistosoma japonicum, Schistosoma mansoni and Trichinella spiralis. These CDS entries have been prefixed with the tag "CDS_<3|4-letter species code>|" (ex. CDS_Cele|...) to make them identifiable amongst other hits. The CDS fasta files being used as blast databases are available in our Data Download section at this link.

As of June 16th, 2017, 30 additional CDS genesets are available as selectable dbs. These represent CDS for a number of additional nematodes that have been added into NemaGene since the previous update. These CDS entries have been prefixed with the tag "CDS_<3|4-letter species code>" (ex. CDS_RSKR...) to make them identifiable amongst other hits, for an index of the prefixes assigned to specific organisms see the NemaGene FAQ. The CDS fasta files being used as blast databases have been made available at this link.
