I am wondering if there is a way to access the MAG sequences used for various taxa genome bins in the MetaPhlAn 4 data base. I know that the supplementary table 1 in the pre-print has a list of GCA Ids and MAG IDs for each taxa, but there is no information about where to access the MAG sequences.

I suspect the answer is currently “no”, based on another post ([About the Metaphlan4 reference genome - #2 by aitor.blancomiguez](https://forum.biobakery.org/t/about-the-metaphlan4-reference-genome/4169/2)), but I’ll remain hopeful. If there is no current list of URLs to access and download MAGs, is there any plans in the future to do so?

Thank you!

Hi @JJGiacomini  
Unfortunately, we do not have the MAGs sequences available, but we are currently working on a system to share all the genomes that will be included in the future ChocoPhlAn(SGB) databases (release date TBD)

Hi @aitor.blancomiguez,

Is there any update on this? It would be off great help for the community if these genomes don’t just exist on your servers. Particularly, when one would use them for phylogenetic or pan-genome analyses.

Thank you!

Hi @alexhbnr  
Unfortunately, we are still working on it
