**What it does**
This tool calculates the Hamming distance for the tags by comparing them to all tags in the dataset and finally searches for the minimum Hamming distance. 
The Hamming distance is shown in a histogram separated by the family sizes or in a family size distribution separated by the Hamming distances. 
This similarity measure was calculated for each tag to distinguish whether similar tags truly stem from different molecules or occured due to sequencing or PCR errros. 
In addition, the tags of chimeric reads can be identified by calculating the Hamming distance for each half of the tag. 
This analysis can be performed on only a sample (by default: sample size=1000) or on the whole dataset (sample size=0). 
It is also possible to select on only those tags, which have a partner tag (ab and ba) in the dataset (DCSs) or to filter the dataset after the tag's family size. 
This tools expects a tabular file with the tags of all families, their sizes and information about forward (ab) and reverse (ba) strands::

**How to generate the input**

The first step of the `Du Novo Analysis Pipeline <>`_ is the **Make Families** tool that produces output in this form::

    1                        2  3     4

   we only need columns 1 and 2. These two columns can be extracted from this dataset using **Cut** tool::

    1                        2 

   now one needs to count the number of unique occurencies of each tag. This is done using **Unique lines** tool, which would add an additional column containg counts (column 1)::

    1 2                        3 
   these data can now be used in this tool.
The output is one PDF file with the plots of the Hamming distance, a tabular file with the data of the plot for each dataset and a tabular file with tags that are chimeric.
