Hi, I am from computer science background. As I am new to bioinformatics I am wondering is there any resource (book, workshop, blog, online course, etc) focusing on practical aspects of the different biological data? Particularly is there any resource on how to process expression data (both array based and NGS based RNA-seq) and methylation data (450k array, WGBS, and RRBS)? It seems I am comfortable with the machine learning part but I have issues with the preprocessing part like do I have to normalize WGBS based bedgraph file or not? I feel that I need a hands-on tutorial on these parts. It will be very helpful if you give me some suggestions? Mainly what to do after getting the fastq files.
