I'm trying (and failing) to get the UCSC genome browser to output what I
need, and would appreciate guidance.

My goal is to get essentially the refFlat table data for the knownCanonical
transcripts.

In other words, I want to get GTF encoded information about transcripts,
with the gene/transcript names flattened into the data, but I only want to
see data for canonical transcripts, not all possible.

Can this be done directly? If not, any suggestions for how to most simply
approximate it by merging things on my end?

The settings I've tried look like this:



but this gives me lines like:

chr1>---hg19_knownCanonical>----exon>---322037>-326938>-0.000000>-------.>------.>------gene_id
"gene9"; transcript_id "tx9";-

where "gene9" and "tx9" are just iterative line-by-line counters that are
clearly meaningless because they never repeat. Meaning that each exon has a
unique (and numerically matched) "transcript" and "gene" label with no
semantic content.

And also I don't appear to get strand information.

In the past I know I've been able to get BED files that contained strand
info and at least grouped exons by transcript, though I don't recall the
settings that got me there...

Anybody see what I r doin rong, here?

Thanks,

-John
