Wrapper function for running trimmomatic program within python
Trimmomatic will remove low quality bases from the ends of NGS reads using an average quality score in a given window size
Parameters
----------
files : string or list of strings
List of input filenames (fastq or fastq.gz) for the MISEQ files. We either accept a single string or a list of two strings.
working_directory : string, default none
Pathname of desired output directory
outfile : string, default empty string
Desired filename name
method : SE or PE, default 'SE'
String representing whether to treat input files as single (SE) or paired-end files (PE)
phred : integer, default None
If None, then will rely on trimmomatic to guess the quality encoding. If a number, then will pass this value into the phred field.
optional_parameters : dict, default empty parameters
An optional dict of all parameters you would like to pass to trimmomatic
