Is there an easy way to separate a large fastq file of raw reads in half? I would imagine this should be pretty easy. I want to see how assembling half of my reads would do with some command... but I also have access to CLC and there doesn't seem to be a way to specify 50% of reads. This is a 70M+ 100 bp dataset.

In analogy to the above:
$ wc -l file.fastq
100 file.fastq
$ head -n 50 file.fastq > halfAFile.fastq

Code:split -n 2 file.fa file.split.fa. # for splitting a file into two

The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...-
