Answer: A: WGS phylogenetic analysis
... For anyone else needing an answer, what I ended up doing was using kSNP3 to do phylogenetic analysis of the fasta files from WGS of 7 genomes. It worked quickly and gave me the result I was looking for - phylogeny based on whole genome sequence data. In my case, it found over 600,000 SNPs and uses t ...

WGS phylogenetic analysis
... My company has been asked by regulatory officials to confirm the species of a filamentous fungus we use for fermentation processes. Specifically we are asked to "Provide unambiguous identification of the organism at the species level through phylogenetic analysis by comparing the whole genome sequen ...

Comment: C: Setting Up Model in DeSeq2
... Well, my concern is this. There's appears to be some large variation between samples that is not accounted for by the diet (here U vs. AO) or the time point (0, 60, 240). Also the histogram of the p values is not what I expect to see? I've added links to graphs to the original question. ...

Comment: C: Setting Up Model in DeSeq2
... Thanks for pointing me there - I was able to use the grouping variable tactic. Then I can compare group C_time0 vs group A_time0 and so on and so forth. The only problem is, when I pull out the results using results(dds, contrast = c("group", "C_time0", "A_time0") all the adjusted p values are eith ...

Setting Up Model in DeSeq2
... I usually stick to genome seq data, so this is my first time using deseq2. I have RNAseq data from Drosophila that were fed either a control diet (C) or supplemented diet (A) while under going physiological stress. They were sequenced at three time points during the experiment. I have the following ...

The table I have has the following columns - sample ID, time ID, treatment ID, number with no blast hits, k__Archaea;p__Crenarchaeota, k__Archaea;p__Euryarchaeo ...

Evaluation of PacBio only de novo assembly
... Does anyone have experience using validation/evaluation methods (other than basic statistics like N50) for a PacBio only de novo assembly? What would you recommend? Note: I don't have multiple assemblies to compare, just want to try to do some validation of a single de novo assembly. ...
