[Genome] changing your assembly reference

[Anthony DiBiase]

We know the zebrafish assembly is incorrect for a specific gene locus
(approx. 250K basepairs).  Is there a way to load in our own (correct) data
for this locus as a new reference assembly (which we would then make custom
tracks against) ?  

 

If not possible with the UCSC genome browser, is there another tool you'd
recommend (e.g. Broad's Argo) ?
