The flowchart below illustrates the general workflow of what to do for the gene expression data analysis. You can click on each part to learn the operations associated with it. It's convenient to pick a topic you want to learn quickly. In the tutorial, on the other hand, you can experience through this workflow on a single data set.
You can also teach yourself using the free resources above, but you may need some prerequisite knowledge and experience. If you find it difficult, we recommend Online Training, although there is a fee.
If you don't have the time to analyze, or if you analyze only a few data sets a year, we recommend Data Analysis Service. As we explain at "What is the most effective way to learn the omics data analysis?", it is more efficient for you to leave the less important tasks to us, and you focus on the critical part, understanding and interpreting data.
