Hello.
I am currently working on a laboratory evolution project. I have a background in molecular biology and are a bit lost with the bioinformatics.
My project involves the culturing of a specific bacterial isolate under different stress conditions for several generations. This was done for 3 different conditions in triplicate, after which the DNA (as well as that of wild-type/reference) was extracted and send for full genome sequencing. The genomes were sequenced on the llumina Miseq platform (2 x 250) using the nextera xt kit for library preparation. So far I have removed the nextera primers with Trimmomatic and have assembled the genomes de-novo using SPAdes, IDBA and CLC, with SPAdes yielding the best assemblies based on Quast analysis. The assembled genomes consisted of ~100 contigs (100 bp cutoff). I also annotated the genomes using the Prokka pipeline.
What would be the next logical steps to take if I want to compare the genomes with the reference. Can this be done visually using the contigs, or should they first be re-ordered/align with closely related genomes. If so, what suitable software can be used?
Any help/guidance will be greatly appreciated. Thank you in advance.
