[ensembl-dev] merging different compara masters

[Lel Eory]

Hello Compara-team,

Can I merge two compara databases from different masters when the 
reference genome is shared between the databases, but are represented 
with different genome_db_ids?
In my case I use a compara master DB to keep track of my pairwise 
alignments and I use Ensembl core chicken (Galgal4 with genome_db_id=1) 
as a reference. In Ensembl compara there is the 4 sauropsids EPO 
alignment which also has Ensembl core chicken in it (Galgal4 with 
genome_db_id=142). The different genome_db_ids break the consistency 
between the data-sets.

Is there a script I can use which would merge the data-sets and would 
make the reference genome_db_id consistent for the alignments (e.g. set 
the same reference genome_db_id for the LastZ and EPO species_sets, 
dnafrags etc.), so that I would be able to use the merged data to create 
the EPO_LOW_COVERAGE alignment?

Thank you.

Best wishes,
Lel
