Hi Lee,

If you have BAM from your Illumina sequencing run, and can put .bam and .bai 
(index) files on a web server, then we can display the BAM as a custom track by 
fetching only the parts of the file that are needed for display.  Instructions 
are here:

http://genome.ucsc.edu/goldenPath/help/bam.html

Since you have paired-end data, I recommend adding the "pairEndsByName=." 
setting described there.  

If you have more questions, please send them to us at [email protected] .

Angie
