Track Hubs allow a lab to share and +host all their genomic data (<a href="help/bam.html">BAMs</a>, <a href="help/vcf.html">VCFs</a>, +ect.) via a single Genome Browser link. Such links can load multiple hubs and even be combined with +a position parameter to easily reference laboratory data around a gene of interest, see examples in +a recent <a href="https://bit.ly/UCSC_blog_sharing">blog bost</a> about sharing data with URLs.</p> +<p> +The <a href="help/hubQuickStartFilter.html">Track Hub Filters Quick Start Guide</a> provides example +hubs employing new extensive <a href="help/trackDb/trackDbHub.html#filter">filter</a> settings +available for Track Hubs.</p> +<p> +The help page is divided into three sections: +<ul> +<li>filter.fieldName - Used for numerical data</li> +<li>filterText.fieldName - Used for text filtering</li> +<li>filterValues.fieldName - Used for filtering by pre-specified values or categories in data</li> +</ul></p> +<p> +The <a href="help/hubQuickStartFilter.html#filterText">filterText.fieldName</a> section discusses +settings that allow to filter items in a hub with names as seen with this screenshot of only +displaying items starting with BRCA using the wildcard match "BRCA*".</p> +<p class ="text-center"> + <a href="https://genome.ucsc.edu/s/Lou/filterTextExample1"> + <img class="text-center" src="help/examples/hubQuickStartFilter/filterTextExample1.1.png" width="800px"> + <img class="text-center" src="help/examples/hubQuickStartFilter/filterTextExample1.2.png" width="45%"> + </a> +</p> +<p> +The <a href="help/hubQuickStartFilter.html#filterValues">filterValues.fieldName</a> section discusses +how to display a drop-down list of options to select items as seen with this screenshot of filtering +items that are labeled as either a "DNA-binding region" or "alpha helix" or +"beta strand".</p> +<p class ="text-center"> + <a href="http://genome.ucsc.edu/s/Lou/filterValuesExample2"> + <img class="text-center" src="help/examples/hubQuickStartFilter/filterValuesExample2.1.png" width="800px"> + <img class="text-center" src="help/examples/hubQuickStartFilter/filterValuesExample2.2.png" width="45%"> + </a> +</p> +<p> +Each section of the <a href="help/hubQuickStartFilter.html">Track Hub Filters Quick Start Guide</a> +comes with examples and sessions allowing to quickly click into real interactive +demonstration hubs to experiment with how the settings work.
