# How to Ray with 454 reads For single reads, just use mpirun -np 9999 Ray \ -s HFIEHFUE.sff -s KFKOEOKFE.sff For paired reads, you must extract manually the reads. convert-sff.sh is available at https://github.com/sebhtml/454-pairs It utilises ssf_extract to get reads from the sff file. Then, it create 3 files: outputPrefix.Reverse.fastq outputPrefix.Forward.fastq and outputPrefix.Single.fastq The 2 first should have the same number of entries. To give them to Ray: mpirun -np 133 \ -p outputPrefix.Reverse.fastq outputPrefix.Forward.fastq \ -s outputPrefix.Single.fastq
