Does cicero include negative correlations in co-accessibility? #72

Closed decapicone closed 3 years ago

decapicone commented 3 years ago

Hi, I am just wondering if the cis co accessible networks contain peaks that are inversely correlated with the rest of the network. I see some values in my conns dataframe (from run_cicero) are negative. So this means that inversely related peaks are also included in the networks, right?

Most of the documentation talks about co-accessibility which makes it seem like it only counts positive correlations.

Thanks, any insight appreciated!

Hello, yes, negative correlations are also calculated, which as you said would be inversely correlated. We in general had a hard time interpreting and validating these connections which is why we don't spend much time on them in the paper or documentation. I have heard from others of instances showing up where it seems like perhaps two competing orientations are showing up as negative correlations... would certainly be interesting to explore. Hope this helps!

@hpliner do the negative values in conns dataframe mean the correlation is negative?

Thanks

@danielcgingerich Yes, they do.
