Cases

No reference assembly

One data set, multiple denovo assemblers

Example:

 * Solexa data
 * edena & velvet assemblers

Solutions:

 * merge 2 assembly sets
 * run minimus on them

Multipls data sets, one(multiple) denovo assemblers

Example:

 Solexa & 454 data
 velvet assemblers for each set

One reference assembly

Multiple reference assemblies
