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 0.0.14 by assafgordon@gmail.com

       [-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
