MasonFragSequencing

Given a FASTA file with fragments, simulate sequencing thereof.

This program is a more lightweight version of mason_sequencing without support for the application of VCF and fragment sampling. Output of SAM is also not available. However, it uses the same code for the simulation of the reads as the more powerful mason_simulator.

You can use mason_frag_sequencing if you want to implement you rown fragmentation behaviour, e.g. if you have implemented your own bias models.
