     longDescription = ''
-      A sequence aligner for protein and translated DNA
-      searches and functions as a drop-in replacement for the NCBI BLAST
-      software tools. It is suitable for protein-protein search as well as
-      DNA-protein search on short reads and longer sequences including contigs
-      and assemblies, providing a speedup of BLAST ranging up to x20,000.
+      DIAMOND is a sequence aligner for protein and translated DNA searches, designed for high performance analysis of big sequence data. The key features are:
+      - Pairwise alignment of proteins and translated DNA at 100x-10,000x speed of BLAST.
+      - Frameshift alignments for long read analysis.
+      - Low resource requirements and suitable for running on standard desktops or laptops.
+      - Various output formats, including BLAST pairwise, tabular and XML, as well as taxonomic classification.
 
-      DIAMOND is developed by Benjamin Buchfink. Feel free to contact him for support (Email Twitter).
