Hello, I learned how to do a RNA-seq using Galaxy, without use the terminal. But then, we you want investigate your results deeply, search/plot specific genes or make a heatmap with some selected genes you need to learn how to use R and cummeRbund.
I didn't know R very well, so I wrote a python module to plot gene expression and heatmap from Galaxy cuffdiff output. Usually python is easier to learn for a newbie.
You can install it using pip or conda-forge. Any feedback or suggestion would be appreciate.
