**What it does**

This script should be applied to generate a useful tree when aligning against a 
template alignment (e.g., with PyNAST). This script will remove positions which 
are gaps in every sequence (common for PyNAST, as typical sequences cover only 
200-400 bases, and they are being aligned against the full 16S gene). Additionally, 
the user can supply a lanemask file, that defines which positions should included 
when building the tree, and which should be ignored. Typically, this will differentiate 
between non-conserved positions, which are uninformative for tree building, and 
conserved positions which are informative for tree building. FILTERING ALIGNMENTS 
WHICH WERE BUILT WITH PYNAST AGAINST THE GREENGENES CORE SET ALIGNMENT SHOULD BE 
CONSIDERED AN ESSENTIAL STEP.

The output of filter_alignment.py consists of a single FASTA file, which ends with 
&quot;pfiltered.fasta&quot;, where the &quot;p&quot; stands for positional 
filtering of the columns.
