For those who may happen to reach this thread by way of search in future you can convert a fasta file to fastq format using `reformat.sh` from [BBMap][1] suite. 

Please remember that the Q-scores created here are fake (example below sets Q-scores to 35 for all bases).

 `reformat.sh in=test.fa out=fake.fq qfake=35`
