[ensembl-dev] motif features - what's a "good" score?

[Ilias Lavidas]

Hello Julie,
Defining a specific cutoff score is not very easy, as this is something 
that varies across cell types.
Since we are focused on potential binding within our predicted 
regulatory elements, we picked a non strict p-value of 0.01 so that we 
wouldn't miss potentially interesting sites.

There is a subset of our motif features that we label as 'experimentally 
verified' and could potentially be of higher value to you.
This subset contains features that fully overlap with a relevant 
ChIP-Seq peak.
At the moment, there is no way to easily retrieve this subset in gff 
format, but we'd be happy to offer this option if this seems useful to you.

Regards,
Ilias
