This is my first exposure to bioinformatics, so please bear with me. For a HS assignment, I chose DNA methylation and breast cancer as my topic. I want to explore the correlation between DNA methylation and gene expression in cancer but am overwhelmed with data such as TCGA. Thus I am looking for processed data where I'm able to apply simple statistical analyses but still draw valid conclusions. I saw many mentions of R programming, but I know nothing about this. I came across MExpress and the MENT database but am not sure how to select the right genes etc.
How should I focus my question and/or what logical steps can I take? Please help me find simplified methods.
Any replies or redirect to links would be extremely appreciated. Thank you so much.
