Quality check on sequencing reads | NGS read preprocessing in R (Part 2)

[@lamjennygrace623]

Thank you so much for such a nice tutorial. Can I please have some questions? 1. as I can see here, you took the available data in package QuasR and I wonder how can I input my own data, which is already contained in my folder? how can I assign my data into FastqFiles? 2. after writeFastq( ), how can I find my Qfiltered files to do QC again? as they don’t show up in my working directory or any folder related. 3. Is there any chance that the Quality boxplot of Qfiltered file looks the same as the one of original fastq file? even though its size was actually decreased from 1.2GB to 4.6KB, for example.
