Hello,

When I polishing, I then received this message:

Thank you in advance

Hi wdp9966,

as the error message suggest, you don't have enough memory when running pilon. We did not offer an option within OPERA-MS for this issue but you can modify your OPERA-MS code this way.

In OPERA-MS.pl line 1141, you can add a java parameter this way:

run_exe("java -jar -Xmx80G $pilon_path --fix bases --threads $num_processor --genome $temp_contig --bam $temp_contig.bam --outdir $polishing_dir > $polishing_dir/pilon.out 2> $polishing_dir/pilon.err");

In this example, I specified 80G of memory. FYI - it is possible that Pilon requires a minimum memory size. I recommend running OPERA-MS on a computer with more memory if you can.
