 <h1>Graphics: No permission is needed to reproduce a graphic produced by the Genome Browser</h1>
 <p>Permission is granted for reuse of all graphics produced
 by the UCSC Genome Browser website. There is no need to contact us to get permission. If your 
 publisher, notably Elsevier, insists on getting approval, please direct them to this webpage.

 <h1>Data: No license is needed for the data files and database tables used by the Genome Browser</h1>
 <p>
 As far as the UCSC Genome Browser group is concerned, the raw table data and binary
 files used to create the graphics by the browser is freely available for both
 public and commercial use. This applies to data that is downloaded as files via 
 http, https, ftp or rsync, and equally when data is accessed through

 cases, the genomes come with citation requirements. The README.txt file in the
 download directory of each assembly shows the
 original restrictions pertaining to the genome
 sequence itself by the original authors; most assemblies do not have any restrictions.

 <p>
 Certain genome annotation data, mostly on the human
 genome and in the domain of clinical genetics, have specific restrictions.
+For some of these, we are not allowed to make the data available. 
 Usually the data must be obtained from the source database directly in the
 original format or licensed, rather from UCSC. Examples are HGMD, LOVD, OMIM, Decipher,
-Genomenom, Genehancer and COSMIC, as well as any GISAID-derived data on viral

 The majority of the Genome Browser source code is available under the
 MIT license, see 
 <a href="https://github.com/ucscGenomeBrowser/kent/blob/master/LICENSE" 
 target=_blank>the LICENSE file in our source code repository</a>. As such, the

 Unix command line utilities</a> needed to build 
 tracks, track hub files, computational pipelines, and our
 hundreds of tools to filter, sort, rearrange, join, and process genome
 annotation files can be used and redistributed freely 
 via package managers and installation tools, even for commercial use (except BLAT/LiftOver).  
 Notable examples are bedToBigBed, wigToBigWig, overlapSelect, featureBits,
 pslMap, pslFilter and pslCDnaFilter.  </p>
