 <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. 
 However, when you use the UCSC Genome Browser in your work, please cite one of our

 As for genome annotation data, a handful of tracks, mostly on the human
 genome and in the domain of clinical genetics, have specific restrictions, 
 usually the data has to be obtained from the source database directly in the 
 original format or licensed. Examples are HGMD, LOVD, OMIM, Decipher,
 Genomenom, Genehancer and COSMIC, as well as any GISAID-derived data on viral
 genomes. Please see the respective track documentation pages on these
 assemblies for more details, by selecting the assembly and clicking the track
 title in the genome browser.</p> <br>
