Hi, I am doing a de novo assembly and I have contamination with Saccharomyces. I cleaned the raw reads (paired reads 150nt) using BBsplit, minimum identity 0.95, but now that I have repeated the assembly I have checked and I still have several contigs which match perfectly or almost perfect with Saccharomyces. What should I do? Repeat the cleaning in the raw reads with lower minimum identity? Cleaning the merged reads? Cleaning the assembly? Thanks!
