<p>Reproducible Analysis Pipeline for Data Streams (RAPIDS) allows you to process smartphone and wearable data to <a href="features/feature-introduction/">extract</a> and <a href="features/add-new-features/">create</a> <strong>behavioral features</strong> (a.k.a. digital biomarkers), <a href="visualizations/data-quality-visualizations/">visualize</a> mobile sensor data and <a href="workflow-examples/analysis/">structure</a> your analysis into reproducible workflows.</p>
<p>RAPIDS is open source, documented, modular, tested, and reproducible. At the moment we support smartphone data collected with <a href="https://awareframework.com/">AWARE</a> and wearable data from Fitbit devices.</p>

<h2 id="how-does-it-work">How does it work?<a class="headerlink" href="#how-does-it-work" title="Permanent link">&para;</a></h2>
<p>RAPIDS is formed by R and Python scripts orchestrated by <a href="https://snakemake.readthedocs.io/en/stable/">Snakemake</a>. We suggest you read Snakemake&rsquo;s docs but in short: every link in the analysis chain is atomic and has files as input and output. Behavioral features are processed per sensor and per participant.</p>
<h2 id="what-are-the-benefits-of-using-rapids">What are the benefits of using RAPIDS?<a class="headerlink" href="#what-are-the-benefits-of-using-rapids" title="Permanent link">&para;</a></h2>
<ol>
<li><strong>Consistent analysis</strong>. Every participant sensor dataset is analyzed in the exact same way and isolated from each other.</li>
<li><strong>Efficient analysis</strong>. Every analysis step is executed only once. Whenever your data or configuration changes only the affected files are updated.</li>
<li><strong>Parallel execution</strong>. Thanks to Snakemake, your analysis can be executed over multiple cores without changing your code.</li>
<li><strong>Code-free features</strong>. Extract any of the behavioral features offered by RAPIDS without writing any code.</li>
<li><strong>Extensible code</strong>. You can easily add your own behavioral features in R or Python, share them with the community, and keep authorship and citations.</li>
<li><strong>Timezone aware</strong>. Your data is adjusted to the specified timezone (multiple timezones suport <em>coming soon</em>).</li>
<li><strong>Flexible time segments</strong>. You can extract behavioral features on time windows of any length (e.g. 5 minutes, 3 hours, 2 days), on every day or particular days (e.g. weekends, Mondays, the 1<sup>st</sup> of each month, etc.) or around events of interest (e.g. surveys or clinical relapses).</li>
<li><strong>Tested code</strong>. We are constantly adding tests to make sure our behavioral features are correct.</li>
<li><strong>Reproducible code</strong>. If you structure your analysis within RAPIDS, you can be sure your code will run in other computers as intended thanks to R and Python virtual environments. You can share your analysis code along your publications without any overhead.</li>
<li><strong>Private</strong>. All your data is processed locally.</li>
</ol>
