visualizing strand-specific read coverage per position

[P-Richmond]

Hello,
I'm looking to display strand-specific RNA-seq data coverage data. I currently generate per-position strand specific coverage using genomeCoverageBed (genomeCoverageBed -ibam <in.bam>-d -s +[-]), but I wanted to see if there was a file-format where I could display both coverages in the same file. I imagine something like this:

chr \t position \t positive_score \t negative_score
chrI 1 0 0
chrI 2 0 0
chrI 3 0 0
...
chrI 30299 29 11
...
chrI 200399 39 2293


or via the WIG format:
chr = chrI; step = 1; span=1
29 -11
39 -2293

for every position in the genome.

Thanks for your help,
Phil
