Are you suggesting that it is not ideal to run the alignment on an entire fastq file? but a partition of the fastq file? Does it matter if the project is DNA ? or RNAseq?

Thank you.
I am just confused because I normally run the alignments on a complete fastq file, and not a partition of a fastq file.

Is there a resource that you'd recommend?
No, its not an issue if you decide to run the alignment of an entire fastq file against the entire reference sequence.

I was suggesting the preferred way of doing the task in parallel to may be utilize a HPC cluster if you have access to one. You'd rather split the fastq file than split the reference file for parallelism.
