NAME
       samtools	dict - create a	sequence dictionary file from a	fasta file

SYNOPSIS
       samtools	dict ref.fasta|ref.fasta.gz

DESCRIPTION
       Create a	sequence dictionary file from a	fasta file.

OPTIONS
       -a, --assembly STR
		  Specify the assembly for the AS tag.

       -A, --alias, --alternative-name
		  Add an AN tag	with the same value as the SN tag, except that
		  a  "chr" prefix is removed if	SN has one or added if it does
		  not.	For mitochondria (i.e.,	when SN	is "M" or  "MT",  with
		  or without a "chr" prefix), also adds	the remaining combina-
		  tions	of "chr/M/MT" to the AN	tag.

       -H, --no-header
		  Do not print the @HD header line.

       -l, --alt FILE
		  Add  an  AH  tag  to	each  sequence listed in the specified
		  bwa(1)-style .alt file.  These files use SAM records to rep-
		  resent alternate locus sequences  (as	 named	in  the	 QNAME
		  field) and their mappings to the primary assembly.

       -o, --output FILE
		  Output to FILE [stdout].

       -s, --species STR
		  Specify the species for the SP tag.

       -u, --uri STR
		  Specify  the	URI  for  the UR tag. Defaults to the absolute
		  path of ref.fasta unless reading from	stdin.
