 <h2>Displaying personal annotation data in the Genome Browser</h2>
 <p>
 <h6>How do I display my own personal annotation data in the Genome Browser?</h6>
 <p> 
 To create an annotation track that will display on the Genome Browser, you must first organize your 
 data into a format supported by the browser custom track feature:

 <h2>BedToBigBed and other utilities fail because of custom track header lines</h2>
 <h6>Why does my custom track fail when I use <code>bedToBigBed</code> or utilities like 
 <code>validateFiles</code>?</h6>
 <p>
 These utilities can fail when the input includes custom-track-specific lines at the top of the file 
 that are not considered part of the data. Many of the custom track examples on the 
 <a href="FAQformat.html" target="_blank">File Format</a> page include a &quot;<code>track 
 type=...</code>&quot; line that is specific for loading the data into the Browser. This line will 
 cause raw data files to fail validation by other tools, such as <code>bedToBigBed</code> or 
 <code>validateFiles</code>, outside of the Browser. To see an example of using 
 <code>bedToBigBed</code> with correct input data types, follow this 
 <a href="../goldenPath/help/bigBed.html#Ex3" target="_blank">link</a>. More information about track 
 lines can be found <a href="../goldenPath/help/customTrack.html#TRACK" target="_blank">here</a>.</p>

+<h2>Non-UCSC style chromosome names</h2>
+<h6>Can I upload a custom track with chromosome names (e.g. '1' or 'NC_000001.11') that don't
+match the UCSC-style chromosome names (e.g. 'chr1', 'chrX')?</h6>
+<p>
+As of 2018, you can upload a custom track that contains either
+UCSC-style chromosome names (e.g. 'chr1', 'chrX') or one of several supported
+aliases, typically from Ensembl (e.g. '1' or 'X'), Genbank (e.g. 'CM000663.2'
+or 'CM000685.2'), or RefSeq (e.g. 'NC_000001.11' or 'NC_000023.11'). Many
+different custom track types support this, including BED, BAM, and any of
+our big* formats like bigBed or bigWig. You can view the list of supported
+aliases by clicking on the &quot;View sequences&quot; link for your assembly assembly of
+interest from the <a href="../cgi-bin/hgGateway">Assembly Gateway page</a> or
+as a &quot;chromAlias.txt&quot; file from <a
+href="https://hgdownload.soe.ucsc.edu/downloads.html" >our downloads server</a>
+under the link &quot;Genome sequence files and select annotations&quot; for that assembly.
