Comment: C: Introducing Clumpify: Create 30% Smaller, Faster Gzipped Fastq Files. And remov
... I develop and test BBTools under Oracle JDK. For most programs, there's no significant difference between Oracle and OpenJDK. However, in some programs that use nearly all available memory, the conditions for memory crashes are different, as the two JVMs manage memory differently. For example, I ...

Comment: C: Introducing CrossBlock, a BBTool for removing cross-contamination
... Hi Andrew, Yes, a log file would be essential here so I can see what phase it's stopping at. Additionally, the entire command line, and contents of readnamefile and refnamefile (if you used those), would be helpful, as would the BBMap version. To clarify, are these transcriptomes of three differe ...

Answer: A: How to make variant calling run faster?
... You can make variant-calling much faster by using BBMap's callvariants.sh tool (which is fully multithreaded) on a raw, unsorted sam file, so you don't have to waste time sorting, indexing and compressing/decompressing bam. It works on bam files too, though, so if you want to use a bam as input I s ...

Answer: A: Unsynchronized simultaneous reads on a single .bam file
... Simultaneous reads don't cause problems; concurrency problems only occur when there is a mix of reads and writes. 100% reads or 100% writes are fine (100% writes is fine because the data is never read so the final state cannot be observed). Some filesystems may perform better or worse with lots of ...

You might be able to get a useful value by also incorporating the standard deviation, some other measure of variance, and/or additional variables, but not with a single universal closed-form equation using the coverage alone.
