GlimmerHMM output

[arkal]

Hey guys,

I'm using glimmerHMM to predict genes from a genome. I'm curious about the concept of the negative strand. Take the example file below

GlimmerHMM
Sequence name: ABCDE
Sequence length: 580 bp

Predicted genes/exons

Gene Exon Strand Exon Exon Range Exon
# # Type Length

1 1 - Terminal 139 144 6

Since it lies on the negative strand, does it mean that the region begins at position 139 (on a 1 to 580 scale) moving forward or from position 580-139+1 = 442 going backwards?

Sorry if this is something trivial i've overlooked,

Thanks in advance,
-A
