@cdunn2001, thanks. I was able to run your examples and I get the same failures
you report. On Ubuntu (14.04 and 16.04) I get a seg fault in the 'make fail'
step at slightly different places
Ubuntu 14.04: (16GB memory)
../main.exe --output_multi --min_idt 0.70 --min_cov 4 --max_n_read 500
--n_core 1 > out.nim.fasta < data/la4.huge/huge.la4falcon
main(n_core=1)
len(seqs)=25, seed_id=2
Segmentation fault (core dumped)
and with 16.04: (with 8GB memory)
../main.exe --output_multi --min_idt 0.70 --min_cov 4 --max_n_read 500
--n_core 1 > out.nim.fasta < data/la4.huge/huge.la4falcon
main(n_core=1)
len(seqs)=25, seed_id=2
len(seqs)=98, seed_id=14
len(seqs)=58, seed_id=15
len(seqs)=43, seed_id=22
len(seqs)=55, seed_id=25
Segmentation fault (core dumped)
so it makes it a bit farther even with half the memory. On OS X Sierra (8GB) it
just hangs right away, as you described.
I'll find some time later to dig deeper; hopefully with this or an even smaller
test case we can find the problem.
