Re: [Mauve-users] progressiveMauve - signal 11

[Aaron D. <aar...@ut...>]

Hi Rosie, apologies for the late reply, I am catching up on email and
think the answer may be useful for others even if you have moved on
from this work.
First, the --scratch-path options control use of temporary storage when
building sorted seed lists (sslist index files) for very large genomes
where a single genome's index will not fit into RAM. In your case it
will not have an effect because S. aureus genomes are fairly small. I
would suggest running without those options and if it still exits with
signal 11 (segmentation fault), it is possible that you need a machine
with more RAM. The total amount of disk space required should not be
more than a 10-20 GB for 100 genomes of the size of S. aureus. That
said, progressiveMauve's compute time grows at least cubically in the
sequence count, so you may find that it is too slow to align more than
50 or so genomes at once.
Best,
-Aaron
