<h1>glam2mask Manual</h1>
<p>This program masks a glam2 motif out of sequences, so that weaker
motifs can be found. Masking replaces residues aligned to key
positions with the symbol 'x'. By alternately applying glam2 and
glam2mask several times, it is possible to find the strongest,
second-strongest, third-strongest, etc. motifs in a set of
sequences.</p>
<ul>
<li>Mask the top motif in my_motif.glam2 out of my_seqs.fa, and store
the result in mask1.fa:
<pre>
glam2mask -o mask1.fa my_motif.glam2 my_seqs.fa
</pre>
</li>
<li>Mask the top motif in my_motif.glam2 out of my_seqs.fa, using 'n'
as the mask symbol:
<pre>
glam2mask -x n my_motif.glam2 my_seqs.fa
</pre>
</li>
</ul>
<p>If the sequences do not have unique names, glam2mask may mask the
wrong ones. It also assumes that the order of the sequences does not
change, so don't do that.</p>
