[ensembl-dev] Fetching Age of Base

[Benoit Ballester]

Dear Ensembl, 

I am trying to get the "age of base" as described here :
https://www.ensembl.org/info/genome/compara/age_of_base.html <https://www.ensembl.org/info/genome/compara/age_of_base.html> 

Basically, for a slice like this, I’d like to get those “age”. 
$slice = $hsap_slice_adaptor->fetch_by_region( 'toplevel', '19' , '1581091','1581269');


It has been a while since I last used the ensembl API (prob ~v60), so I wonder if I could get those values from a core slice (which I doubt), most likely from a compara object, but which one ? Is this something stored in the compara db for human, or computed on the fly from a multiple alignment objet ?

The Doxygen doc is not of much of any help for me I am afraid, as I can’t get much info there. 

Any embryo of code to get me on track would be must appreciated.  

I am on version 111 of core and compara. 

Thanks,

Ben
