Dr. Yoo's In Vivo Experiments, First Steps

Confirming a computed gene
in a living body

If the 20 lessons at /gene were about finding DDX54 with ARACNE-VIPER-DIGGIT, these 20 are about confirming that prediction in mice.
Step by step, with runnable cells and widgets, you retrace the hands behind every bar and curve in Fig. 4.

How you'll learn

๐Ÿ“„Start from one line of the paper

Every lesson unfolds one line from the paper's methods. The subtitle of each lesson says exactly which line.

โ–ถ๏ธRun the numbers yourself

Tumor volume, Kaplan-Meier, log-rank, statistical power โ€” all worked out by hand, right in the browser.

๐ŸŽ›๏ธDecide it differently

Remove a group, change the cell count, move the cut-point. You see exactly where the conclusion wobbles.

โš–๏ธOnly what can be claimed

The final lesson separates what this experiment can claim from what it cannot.
