ART_PROFILER_ILLUMINA, Weichun Huang @ whduke@gmail.com
ABOUT 

	This tool is to create an ART illumina read quality profile from Illumina sequencing data
	in multiple fastq or gzipped fastq files
	
USAGE:
       ./art_profiler_illumina out_profile_name input_fastq_dir [fastq_filename_extention (default: fq)]

	or

	bash art_profiler_illumina out_profile_name input_fastq_dir [fastq_filename_extention (default: fq)]
	
PARAMETERS:

       out_profile_name:  the name of read quality profile  
       input_fastq_dir:   the directory of input fastq or zipped fastq files  
       fastq_filename_extension: fastq or gzipped fastq filename extension (default: fq)
	
EXAMPLES:

	1) create hiseq2k profiles from all *.fq.gz in the directory fastq_dat_dir
	./art_profiler_illumina hiseq2k fastq_dat_dir fq.gz

	2) create miseq2500 profiles from all *.fq in the directory fastq_dat_dir
	./art_profiler_illumina miseq250 fastq_dat_dir fq

	3) create hiseq1k profiles from all *.fq in the directory fastq_dat_dir
	./art_profiler_illumina hiseq1k fastq_dat_dir
       	       
NOTES: 
	For paired-end fastq files, e.g., *.fq or *.fq.gz, the filenames of the 1st reads must be *_1.fq or *_1.fq.gz,
       	and those of the 2nd reads must be *_2.fq or *_2.fq.gz,
