Ground truth problem in Sachs
Also an edge from pka to raf is missing.
@cruyffturn Oh thanks! I'll check it out.
Huh, I pulled up the Sachs 2005 article and am staring once again at Figure 2; the edge is in fact pip3->plc. In Figure 3A, they show the plc->pip3 edge, but they show it in purple, which indicates that it is reversed. So it seems that one is OK.
However, pka->raf is definitely missing; I'll add it.
What do you think? @cruyffturn
Also sorry for the delay; I had to find a couple of minutes to get the Sachs article in front of me.
In this page, https://www.bnlearn.com/research/sachs05/index.html, the direction is suggested to be plc->pip3, I am not sure which one is correct.
