[Genome] GC Percent selected fields

[Peter Brooks]

Hello

In Table Browser, I tried to download a table of GC percent with a 
limited choice of fields.
In "output format", only the 3 choices: data points, bed format or 
custom track were available.
Output format did not include the usual prompt "selected fields form 
primary and related tables".
(So the only possible output was the listing of GC% for sequential 5 bp 
segments.)

I tried another type of table and found the "selected fields form 
primary and related tables" as usual in Output format.

Then when I went Back in Firefox, and reselected gc5Base, I was able to 
select fields and download.
So I got the data but I would appreciate any suggestions about how to 
use Table Browser to avoid this problem.

Thank you

Peter Brooks
