Usage: chipcenter [options] [-f <feature>] -s <shift> [<] <SGA file>
      - version 1.6.0
      where options are:
  		 -h         Show this help text
  		 -d         Print debug information
  		 -i <dir>   Directory where the chr_size file is found
  		 -z         Set strand to zero
  		 -c         Count Cut-off (default is 1)
  		 -r         New feature name (for feature replacement)

	Feature Centering Tool for ChIP-seq data analysis.
	The program reads a ChIP-seq data file (or from stdin [<]) in SGA format (<SGA file>), and
	shifts (by <shift>) ChIP-tag positions corresponding to feature <feature> to the estimated
	center-positions of DNA fragments. If no feature specification is set, the program accepts
	all lines of the input SGA. If -r <new_feature> is specified, the feature field is replaced
	with the new <new_feature> string. The program checks whether, after shifting, the new genome
	coordinates are still within chromosome boundaries. Consequently, the file chr_size must be read.
