Scale of the outputs in Enformer

[tammy-dg]

Hi all,

I was wondering about whether the outputs from Enformer for each of its types of tracks -- DNASE, CHIP and CAGE -- are in the log2 space already.

From the colab notebook -- https://colab.research.google.com/github/deepmind/deepmind_research/blob/master/enformer/enformer-usage.ipynb#scrollTo=_wL4c66ZXK0k -- I was wondering why you apply a log transformation to visualize the CAGE tracks in for some tracks (i.e., Keratinocyte track), but not for others (i.e., the neutrofils track).

And for the pre-computed predictions, why would one choose to use the SAD vs the SAR?

Thanks in advance for your time,

Tammy
