The nans in CTX and DEM outputs

[samuelheczko]

Hi all,

First, thank you for developing this amazing tool!

I have a question regarding the NaN values in the annotation columns of the CTX and DEM results. In my analysis, I’ve noticed a significant proportion of NaN values, with the majority of motifs lacking orthology and direct annotations (screenshot attached).

I’m trying to better understand how these NaN values arise. Since the dataset from which we scan the motifs is derived from TF binding experiments like ChIP-seq, I am unsure how it could contain binding motifs that lack annotations.

Would anyone be able to clarify the origin of these NaN values and suggest strategies to reduce them in my results?

Thank you for your time and support!

Kind regards,
Sam
