Hello, I am a high school student working on a research project regarding co-expression. I want to reproduce the r-scores automatically generated when you find correlates on the Allen Human Brain Atlas for a certain probe, but can’t figure out how. When I download the data myself, I put it into Excel and use the =CORREL function, but the r-score is a bit off. For ex., when comparing A_23_P216779 prove for NTRK2 and CUST_1359_PI416573500 probe for NTRK2, the atlas says the r-score is 0.947, but in Excel, I got 0.967605151.
Could anyone help me with this? How do I reproduce these r-scores? It’d be great if the help was a little bit simplified since I am in high school and new to data analysis.
