NAME

       fasta_formatter - changes the width of sequences line in a FASTA file

DESCRIPTION

       usage: fasta_formatter [-h] [-i INFILE] [-o OUTFILE] [-w N] [-t] [-e] Part of FASTX Toolkit 0.0.13.2 by gordon@cshl.edu

       [-h]   = This helpful help screen.

       [-i INFILE]
	      = FASTA/Q input file. default is STDIN.

	      [-o OUTFILE] = FASTA/Q output file. default is STDOUT.  [-w N]	   = max. sequence line width for output FASTA file.

	      When  ZERO  (the default), sequence lines will NOT be wrapped - all nucleotides of each sequences will appear on a single line (good
	      for scripting).

       [-t]   = Output tabulated format (instead of FASTA format).

	      Sequence-Identifiers will be on first column, Nucleotides will appear on second column (as single line).

       [-e]   = Output empty sequences (default is to discard them).

	      Empty sequences are ones who have only a sequence identifier, but not actual nucleotides.

   Input Example:
	      >MY-ID AAAAAGGGGG CCCCCTTTTT AGCTN

   Output example with unlimited line width [-w 0]:
	      >MY-ID AAAAAGGGGGCCCCCTTTTTAGCTN

   Output example with max. line width=7 [-w 7]:
	      >MY-ID AAAAAGG GGGTTTT TCCCCCA GCTN

   Output example with tabular output [-t]:
       MY-ID  AAAAAGGGGGCCCCCTTTTAGCTN

       example of empty sequence: (will be discarded unless [-e] is used)

	      >REGULAR-SEQUENCE-1 AAAGGGTTTCCC >EMPTY-SEQUENCE >REGULAR-SEQUENCE-2 AAGTAGTAGTAGTAGT GTATTTTATAT
