Hello,
I am trying to run Ray to do hybrid assembly of Illumina (paired end data) and Roche 454 data. I am running the program on server with 64 cores and 512GB RAM
I ran the sample data in Ray; which is working fine.
When I give my data, the program is producing Contigs.fasta output but, giving error before scaffolding.
I ran the following command
$ mpiexec -n 20 ray-build/Ray -k 31 -p mp_R1_trimmed_q20_p100_clipped.fastq mp_R2_trimmed_q20_p100_clipped.fastq -s 454.fastq -o kmer_31_out
After contig buildng program gave the following fault while scaffolding
*** Process received signal ***

*** End of error message ***
--------------------------------------------------------------------------
mpiexec noticed that process rank 19 with PID 21982 on node pragnya exited on signal 11 (Segmentation fault).
--------------------------------------------------------------------------
I tried to run the program with different number of ranks and kmers. But still stoping at scaffolding stage.
Can anyone please help
