Good Evening:
With your own local mirror of the genome browser you can load
your tracks directly into the database. You do not need to load
them as custom tracks. When you load local bigData files,
the entry in the database is simply a local file name, it does
not have to be a URL to an FTP or HTTP server. The loading
sequence is like this:
# create symLink from location where data file exists to a global
# location for everything related to this database:
ln -s `pwd`/localBigData.bam /gbdb/hg19/bbi/
# create the database table, a single column, the contents can be
# this local file name, or a URL to an external resource
hgsql hg19 -e 'drop table if exists localBigData; \
create table localBigData (fileName varchar(255) not null); \
insert into localBigData values
("/gbdb/hg19/bbi/localBigData.bam");'
This will be a lot more convenient than trying to maintain the custom
tracks database.
