       hmmstat - summary statistics for	a profile file

       hmmstat [options] hmmfile

       The hmmstat utility prints out a	tabular	file of	summary	statistics for
       each profile in hmmfile.

       hmmfile may be '-' (a dash character), in which case profiles are  read
       from a stdin pipe instead of from a file.

       The columns are:

       idx    The  index  of  this profile, numbering each profile in the file
	      starting from 1.

       name   The name of the profile.

	      The optional accession of	the profile, or	"-" if there is	none.

       nseq   The number of sequences that the profile was estimated from.

	      The effective number of sequences	that the profile was estimated
	      from,  after HMMER applied an effective sequence number calcula-
	      tion such	as the default entropy weighting.

       M      The length of the	model in consensus residues (match states).

       relent Mean relative entropy per	match state, in	bits. This is the  ex-
	      pected (mean) score per consensus	position. This is what the de-
	      fault entropy-weighting method for effective sequence number es-
	      timation	focuses	 on,  so for default HMMER3 models, you	expect
	      this value to reflect the	default	target for entropy-weighting.

       info   Mean information content per match state,	in bits.  Probably not
	      useful.  Information content is a	slightly different calculation
	      than relative entropy.

       p relE Mean positional relative entropy,	in bits.  This	is  a  fancier
	      version of the per-match-state relative entropy, taking into ac-
	      count the	transition (insertion/deletion)	probabilities; it  may
	      be  a  more accurate estimation of the average score contributed
	      per model	consensus position.

       compKL Kullback-Leibler divergence from	the  default  background  fre-
	      quency  distribution to the average composition of the profile's
	      consensus	match states, in bits.	The higher  this  number,  the
	      more  biased  the	 residue composition of	the profile is.	Highly
	      biased profiles can slow the HMMER3  acceleration	 pipeline,  by
	      causing too many nonhomologous sequences to pass the filters.

       -h     Help;  print  a  brief  reminder	of  command line usage and all
	      available	options.
