Hello, I hate to revisit this, but I am apparently too thick to understand what is happening. I have a dataset (oanatinus_gene_ensembl) for which I am essentially duplicating the Biomart interface. When I use Martview, under Attributes, Variations, Gene, Ensembl, I see 13 attributes. When parsing the dataset myself, I find 17 attributes, none of which exactly correspond to the attributes displayed under the Martview.
When I asked this before, it was explained to me that the 'pointerDataset' attribute points to an external data set that provides the display information that MartView uses. I am not understanding how the 17 attributes that I find correlate to the 13 attributes displayed in the MartView. I can do a query for the remote data, but what I am failing to see is how that remote data set correlates with the original data set.
