I'm interested in creating a small image (5.5" x 1.5") depicting a ~6Mb portion of the dog genome - drawn to scale. I'm interested in including genes and a "ruler" designating every ~500kb. I thought this would be a simplistic task, but I've found that online bioinformatics software gives took much, while photoshop gives too little (doesn't offer self-scaling, from a GB file, etc).
Are there any programs out there that can utilize a sequence file from NCBI, generate a high quality image of a portion of that sequence file, that I can then open in photoshop and continue editing?
I'm looking for something like this - to scale, with a ruler. I'd love the option of zooming in on fractions of the image, and going into more detail, but let's figure out how to bake the cake before we get into the icing.
