I am relatively new in denovo assembly research. I started with 2X100 Illumina data and have used Valvet to generated contigs for identification of bacterial genome. I have ref genome. The idea is to check presence of absence of bacteria in different samples.
My question is once I have contigs what should be my next step to conclude that the said bacteria is present or absent. I was thinking if I can just blast these contigs or align with refrefnce?
How would I found out which Contig is significant which is not.
Is there any rule to check which contig has to be used before I should check their % alignments with ref.?
Any other sophisticated method of confirming if bacteria is present of absent from such seq data, any member may have used in this forum.
