+Galaxy workflow for the identification of candidate genes clusters
+------------------------------------------------------------------
+
+This approach screens two proteins against all nucleotide sequence from the
+NCBI nt database within hours on our cluster, leading to all organisms with an inter-
+esting gene structure for further investigation. As usual in Galaxy workflows every
+parameter, including the proximity distance, can be changed and additional steps
+can be easily added. For example additional filtering to refine the initial BLAST
+hits, or inclusion of a third query sequence.

+
+
+Sample Data
+===========
+
+As an example, we will use two protein sequences from *Streptomyces aurantiacus*
+that are part of a gene cluster, responsible for metabolite producion.
+
+You can upload both sequences directly into Galaxy using the "Upload File" tool
+with either of these URLs - Galaxy should recognise this is FASTA files.

+ * https://raw.githubusercontent.com/bgruening/galaxytools/master/workflows/ncbi_blast_plus/find_genes_located_nearby/WP_037658557.fasta
+
+In addition you can find both sequences at the NCBI server:
