Hi there, Please do not pull your swords immediately, nor ignore. I am doing experimental assemblies with a low coverage 454 Titanium data (a plant). After many assemblies with different settings, and having primers designed for each and all of them, I wanted to test out the primers that occurred in most of the assemblies. So I had more than a hundred primers in wet lab tested, and all of them are working flawlessly. Since I now which primers yield transcripts, I filtered those and tried to find those little sequences in my assemblies. But I could not find all of them in an assembly, while I should find. I thought that having more primers mapped to an assembly might present a higher quality assembly, but for now can not demo. The thing is, when I - I do not now why I did that, maybe it thought it would be fun or something- told mira those reads that I have are ESTs (-job=est), and have an assembly, I mapped the primers I have in hand, and baaam.. ALL of the primers mapped. So, can you please shed some light? I am thinking in a way that does not make sense by mapping the primers? How or why I get those primers mapped to the EST assembly? Best,
