title: Convert sequence list to fasta for multiple files
body: <p>I have thousands of files, which are a list of sequence names followed by their sequence, one individual per line, something like this:</p>
  
  <pre><code>L.abdalai.LJAMM.14363.SanMartindeLosAndes        CCCTAAGAATAATTTGTT
  L.carlosgarini.LJAMM.14070.LagunadelMaule        CCCTAAGAAT-ATTTGTT
  L.cf.silvai.DD.038.Sarco                         CCCTAAGAAT-ATTTGTT
  </code></pre>
  
  <p>And I want to change them to fasta format, so looking something like:</p>
  
  <pre><code>&gt;L.abdalai.LJAMM.14363.SanMartindeLosAndes       
  CCCTAAGAATAATTTGTTCAGAAAAGATATTTAATTATAT
  &gt;L.carlosgarini.LJAMM.14070.LagunadelMaule
  CCCTAAGAAT-ATTTGTTCAGAAAAGATATTTAATTATAT
  &gt;L.cf.silvai.DD.038.Sarco
  CCCTAAGAAT-ATTTGTTCAGAAAAGATATTTAATTATAT
  </code></pre>
  
  <p>I work on a Mac.<br>
  Thanks!</p>
