Hi,
I have some data that I thought would be appropriately displayed using
wiggle tracks. In my data, chromosome 15 (an average length chromosome)
is 85Mb long and has 1600 data points. This is an average of one data
point per 50kb. I am using the variable step data format for loading
the data. Everything works and displays properly but uses a lot of
memory.
When I view a 5Mb region, "top" shows a memory usage (both virtual
and resident memory are roughly the same) by gbrowse of about 330MB.
Viewing a 10Mb region results in 650MB being used by gbrowse.
Viewing a 20Mb region results in 1.2GB being used and I get a timeout.
Do these memory figures seem typical? Is my data not dense enough
for wiggle plots? Ideally, I would like to be able to view an
entire chromosome at once.
