Hi Cristina, not a bother, no need to apologize! In fact, this is really
useful information. I downloaded those two genomes from the NCBI genbank
ftp site and tried to reproduce the error on Mac or Linux. I ran the
alignment 10 times and on Mac it did crash on one of those 10 runs at
the same place you experienced the crash, and on Linux it reported
errors (but did not crash) on some but not all of the runs. So it seems
there is an elusive data-dependent and nondeterministic bug being
triggered here. I will need to dig deeper to understand what's gone
wrong, but in the meantime you might find that running the same
alignment again will work.

Best,
-Aaron
