FASTX-toolkit files copied to your galaxy server directory.

Additionally, you'll need to make the following manual configurations:

1. Add the content of 
	$SRC/galaxy/fastx_toolkit_conf.xml 
   to
	$DEST/tool_conf.xml
	
2. Update the adapters file:

	$DEST/tool-data/fastx_clipper_sequences.txt
	
   And add valid adapters/linkers.
	
3. Edit "fastx_barcode_splitter_galaxy_wrapper.sh", change 
   The two variables BASEPATH and PUBLICURL to valid path/URL.
   See README for detailed explanation (under the
   "Special configuration for Barcode-Splitter" section).
