   <h5>• What does OpenSNP offer me as a genotyping-customers?</h5>
  
positive.code: <h5>• How long does it take until my genotyping data is available on the site after uploading?</h5>
  This heavily depends on how many other users are in the queue, waiting for their data to be parsed. Right now openSNP runs on a small scale server so it may take 2-3 days until all your variations can be found on the site. But you can start using openSNP right away and others can download your raw-data right from the start. The parsing only affects the "other users sharing this SNP" and the "my genotype"-views.
  
  <h5>• I was genotyped by another DTC company, why can't i upload my data?</h5>
  We are always interested in adding more data. If your company is missing up to now it is, because we did not have an example-file to optimize our parser on it. But if you contact us at <%=link_to "parsing@opensnp.org","mailto:parsing@opensnp.org"%> and send us your file we can fix this, so that all customers of the DTC company of your choice can participate.

  <h4>Using DAS</h4>
  <h5>• DAS?</h5>
  We've implemented some basic commands of the <a href="http://en.wikipedia.org/wiki/Distributed_Annotation_System"><em>Distributed Annotation System</em></a> (DAS). Those are for example used for the genome browsers on the SNP-pages in <em>openSNP</em>. 
  
  <h5>• Where can I learn more about DAS?</h5>
  If you want to learn more about the use at <em>openSNP</em> you can <a href="http://opensnp.wordpress.com/2012/02/20/videos-on-opensnp-das-support/">watch this video</a> which explains a bit about it. You can also read the <a href="http://www.biodas.org/documents/spec.html">specifications</a> or read about <a href="http://www.dasregistry.org/DASCommandExamples.jsp">example commands</a> at the <a href="http://www.dasregistry.org/"><em>DASRegistry</em></a>. 
  
  <h5>• How can I see all DAS sources?</h5>
  To find all DAS-sources you can point your browser to <a href="http://opensnp.org/das/sources"><em>http://opensnp.org/das/sources</em></a>. You should get back some XML which roughly looks like this: 
  <pre class="prettyprint linenums">
    &lt;SOURCES&gt;
      &lt;SOURCE uri=&quot;6&quot; title=&quot;6&quot; description=&quot;6&quot;&gt;
        &lt;MAINTAINER email=&quot;admin@opensnp.org&quot;/&gt;
        &lt;VERSION created=&quot;29.09.2011 15:43&quot; uri=&quot;6&quot;&gt;
        &lt;COORDINATES uri=&quot;http://www.dasregistry.org/dasregistry/coordsys/CS_DS40&quot; source=&quot;Chromosome&quot; authority=&quot;NCBI&quot; taxid=&quot;9606&quot; version=&quot;36&quot; test_range=&quot;1:0,1&quot;&gt;NCBI_36,Chromosome,Homo sapiens&lt;/COORDINATES&gt;
        &lt;CAPABILITY query_uri=&quot;http://opensnp.org/das/6/features&quot; type=&quot;das1:features&quot;/&gt;
        &lt;CAPABILITY type=&quot;das1:unknown-segment&quot;/&gt;
        &lt;/VERSION&gt;
      &lt;/SOURCE&gt;
        &lt;SOURCE uri=&quot;10&quot; title=&quot;10&quot; description=&quot;10&quot;&gt;
        &lt;MAINTAINER email=&quot;admin@opensnp.org&quot;/&gt;
        &lt;VERSION created=&quot;29.09.2011 20:54&quot; uri=&quot;10&quot;&gt;
        &lt;COORDINATES uri=&quot;http://www.dasregistry.org/dasregistry/coordsys/CS_DS40&quot; source=&quot;Chromosome&quot; authority=&quot;NCBI&quot; taxid=&quot;9606&quot; version=&quot;36&quot; test_range=&quot;1:0,1&quot;&gt;NCBI_36,Chromosome,Homo sapiens&lt;/COORDINATES&gt;
        &lt;CAPABILITY query_uri=&quot;http://opensnp.org/das/10/features&quot; type=&quot;das1:features&quot;/&gt;
        &lt;CAPABILITY type=&quot;das1:unknown-segment&quot;/&gt;
        &lt;/VERSION&gt;
      &lt;/SOURCE&gt;
    &lt;/SOURCES&gt;
  </pre>
  The title of each source corresponds to a single <em>openSNP</em>-user. Even if users have provided more than one file you can query all the data available for this user through a single DAS-source. 
  
  <h5>• How can I query a DAS source?</h5>
  To query a DAS-source you can use the <em>features</em>-command and provide the chromosome and slice you are interested in. For example <a href="http://opensnp.org/das/1/features?segment=1:1,1000000"><em>http://opensnp.org/das/1/features?segment=1:1,1000000</em></a> will provide you with all SNPs which are located between base 1 and 1000000 for the user with the ID #1. It will produce a similar XML-output like shown below: 
  
  <pre class="prettyprint linenums">

  <div id="api">
  	<h4>Using JSON</h4>
  	We provide some methods to make it easier to get data back from <em>openSNP</em>. Currently we are implementing some <i><a href="http://en.wikipedia.org/wiki/JSON">JavaScript Object Notation</a></i> (short: JSON) methods that will make it easier to code some awesome <em>openSNP</em>-utilizing stuff. As you can see on the Wikipedia-page there are many JSON-parsers around for all major programming languages and it is fairly human readable as well. Plus: It is one of the de facto webstandards for APIs. We are trying to add more of such methods in the near future.
