README:
This D. simulans assembly represents a mosaic of several different D. simulans lines. 
The assembly process began with a ~4X WGS assembly of the the D. simulans w501 line. 
The w501 contigs were initially anchored, ordered and oriented by alignment with the 
D. melanogaster genome. The assembly was then examined for places where the w501 assembly 
suggested inversions with respect to the D. melanogaster assembly. One major inversion was 
found, confirming the already documented inversion found by Lemeunier and Ashburner (1976). 
Six other D. simulans lines (c167.4, md106ts, md199s, nc48s, sim4, and sim6) were assembled 
with ~1X coverage. Using the 4X WGS assembly of the simulans w501 genome as a scaffold, 
contigs and unplaced reads from the 1X assemblies of the other individual D. simulans lines 
were used to cover gaps in the w501 assembly where possible. Thus the resulting assembly 
is a mosaic containing the w501 contigs as the primary scaffolding with contigs and unplaced
reads from the other lines filling gaps in the w501 assembly.
