   We now have everything set up to perform the BLAST search. As we are talking about proteins, we will use blastP. The parameters needed for the Wrapper function are:
  -    - path of the ncbi/bin folder
  -    - path and name of the search database 
  -    - path and name of the query
  -    - path and name of our output file
  -    - a sequence of BLAST parameters, containing any parameters additional to the above (like our customOutputFormat)

   _Note: in this case we can use the string `inputFile` that we used above for creating our database, as we did not specify another path or name for our database. Adjust accordingly if
   done otherwise_
  
positive.code: ---------------------------
  
  We have created our search database and the query we want to find. Before we can perform the actual search, we need to define the BLAST prameters.
  _Note: custom output formats can only be specified for output types `CSV`, `tabular` and `tabular with comments`. For more information, check 
  the [options for the command-line applicaions](http://www.ncbi.nlm.nih.gov/books/NBK279675/)_
  
  First, lets specify the overall output type. This will define the outline of our output. We want our output to be in tabular form, with added information
  in the form of comments.
  _Note: when not specified, the output type will be `pairwise`_

negative.code: Introducing BlastWrapper
  ========================
  
  BlastWrapper is a tool for performing different tasks in NCBI BLAST console applications (version 2.2.31+).
  It is able to create BLAST databases and perform **blastN** or **blastP** queries, while providing a way to set
  output parameter for creating a custom output format.
  Official documentation for all BLAST applications can be found [here](http://www.ncbi.nlm.nih.gov/books/NBK279690).
  
  For the purpose of this tutorial, we will build a protein database using a `.fastA` file containing chloroplast proteins
  of Chlamydomonas reinhardtii included in BioFSharp/docs/content/data.
