I'm an absolute beginner trying to solve this question "Align the trimmed and untrimmed reads using QuasR and plot alignment statistics, did the trimming improve alignments?"

I did trim the reads using the preprocessReads() function, now I want to align the output but the qAlign() only takes a samples file and genome file. however, my trimmed reads are two separate files how can I align them.

I asked google but I didn't find the answer

The QuasR vignette tells you how to run it. The samples file should contain a list of your samples and fastq files.
