C. elegans data sample for Pergola documentation

<p>C. elegans data sample for Pergola documentation (<a href="http://cbcrg.github.io/pergola/quick_start.html">http://cbcrg.github.io/pergola/quick_start.html</a>). The sample data set consists in two folders: One named &quot;worm_speeds&quot; containing a CSV file for each of the tracked worms. From the several measures that can be found in the individual files, in this example we will use mid-body speed. The &quot;mapping&quot; folder contains the &quot;worm_speed2pergola.txt&quot;, which sets the mappings between the information represented in the worm_speed files and the pergola ontology.</p>
