# AlignGraph runs the alignment steps with BLAT and Bowtie2 automatically, but both
# need to be installed on the system. AlignGraph’s run time is currently 23–57 min
# per million aligned reads. In the performance tests of this study, the memory usage
# was 36–50 GB, and it stays <100 GB even for entire mammalian genomes. These requirements
# are more moderate than those of most de novo assemblers (Luo et al., 2012).
# 8 threads are hardcoded. Currently users cannot make changes to this, since this is
# a moderate choice for either single CPU machines (overhead for parallelization would
# not be too large) or multiple CPU machines. Another reason is, the bottleneck for the
# runtime is usually from BLAT, no matter how many threads there are for Bowtie2.
