Better view of metadata fields in track table search #119

Open bnprks opened 5 years ago

bnprks commented 5 years ago

I was recently using the ENCODE public trackhub to look up some human transcription factor ChIP-seq tracks. I found it pretty challenging to find the right tracks to load, however, since the columns the track table shows gave many identical rows without showing the distinguishing metadata for my search.

In this case, the important metadata field was "type", which was either "fold change over control" or "signal p-value". Although it was possible to narrow down the tracks using the full text search, it would be much easier if I could add a metadata column to the table view just like I can add metadata columns in the browser view.

Here's a screenshot showing the somewhat confusing view I got:

[Note: a side issue which made this issue even worse is that the original ENCODE biological replicate metadata appears not to be incorporated in the trackhub metadata, so each experiment also has bioreplicates "1", "2" and "1,2", but it is impossible to distinguish them with the current trackhub metadata]

Hi @bnprks, this is a good suggestion, I will try to make the columns customizable through users. Thanks.
