Good Evening Wuqi:
Please do not worry about what column 9 is called.
If you loaded the table with data in column 9 of
the form r,g,b where r g and b are integers in
the range of 0 to 255, then you are using the itemRgb
option of this column and you already know why.
Otherwise, you loaded this column with 0 because
it is "reserved" and used for nothing.
Please continue to load bed tracks with the hgLoadBed
option. See also, the description of the bed format:
