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.

The head command in Linux also alllows you to extract a number of lines from the start of the file (or use the tail command for the end of the file), without splitting the whole file:
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 field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
