Technically it can transform anything - as long as the data can be transformed into reverse star, then the original data format is irrelevant.
However MartBuilder versions up to 0.7 have trouble with CHADO and similar schemas where all tables refer back to a single central ID table. But in these cases you can still do your own transformations by hand without using MartBuilder - once you have something in reverse-star form then MartEditor can understand it and you can build a mart out of it. There may well be fixes for CHADO-like schemas in the forthcoming 0.8 version of MartBuilder. Arek and co. will let you know I'm sure. cheers, Richard On 15 May 2010, at 01:47, Kan, Zhengyan wrote: > Hi, Bio-mart team: > > I wonder if there are some data sets not suitable for transformation > into Biomart.
