.. class:: infomark

**What it does**

This tool analyzes a collection of sequences in FASTA format and reports: \

 - The total number of sequences.
 - The total number of nucleotide or amino acids.
 - The total frequency of nucleotide or amino acids.
 - The positional frequency of nucleotide or amino acids (optional).
 
-----

**Example**

If the FASTA sequence collection contains these two sequences::

	&gt;UniProtKB:Q42593 L-ascorbate peroxidase T, chloroplastic;
	MSVSLSAASHLLCSSTRVSLSPAVTSSSSSPVVALSSSTSPHSLGSVASSSLFPHSSFVL
	QKKHPINGTSTRMISPKCAASDAAQLISAKEDIKVLLRTKFCHPILVRLGWHDAGTYNKN

The reported stats (without optional positional acid frequencies) will be this::
   
	Sequences	2
	Acid A		69
	Acid C		8
	Acid D		44
	Acid E		44
	Acid F		33
	Acid G		52
	Acid H		18
	Acid I		30
	Acid K		50
	Acid L		67
	Acid M		9
	Acid N		22
	Acid P		46
	Acid Q		13
	Acid R		26
	Acid S		57
	Acid T		23
	Acid V		37
	Acid W		7
	Acid Y		21
	Total acids	676
