 # $] - end position of window
 # $n - current organism name, spaces replaced with underscores
 # $D - current database, like hg19

 # $seq - current sequence in view
 # $taxId - taxon id of current db

 # $position - current position, format chr:start-end
 # $halfLen - 1/2 of the current window size (for pointing external tools to the current center)
