    <help>

   Estimates coverage of a reference genome for bam, bed or gff as a bigwig, suitable for viewing in JBrowse2 or other browser.
 
   A chromosome lengths file must be provided if the input has a missing dbkey='?' on the pencil (edit attributes) tab. 
   
   The actual reference is not needed. The Compute sequence length tool can generate the lengths file.
 
   This can be useful in workflows with assemblies in progress before a stable reference is available for a custom or built in reference dbkey.
