Hi,

sorry, but it appears I cannot find the part  in the table browser where to
filter tables, under

group: comparative genomics
track: eg 28-Way Cons
tables: phastCons28way and others

When I try to use the filter I do not find any setting that allows
specification of any tables but rather settings on positional/score
information.

Under output format I have selected MAF.

I can create an intersection with my custom bed tracks and get conservation
scores for those intervals.

But I do not find where to subset specific tables. I can do this within the
real browser and get a nice display of conservation score for the chosen
genomes.

Could you please point me at the correct place to go!

Kind regards

Maxim
