Standard protocol at this point. Use the rep sequences to find integrase genes, similarity to bacterial genomes, and similarity to aclame genes.
Too "back-of-the-envelope". It really needs to be redone after QC.
Once we get the samples pooled, we need to submit them to the sequencing core to be run on the HiSeq4000 platform.
The last time I ran the contig cat, there was a problem causing a bunch of reads to mix together. Probably due to a parallel run.
I fixed it but the files need to be remade.
Problem is that it is running out of memory and dying.
Need a section to correct for alignment length.
You know the drill.
This means that I need to identify the bacterial OGU(s) that is(are) fusobacteria, and then plot the average degree centrality for the three disease categories.
Some of the sequence IDs are wrapped up in with the sequence before it, so I need to make sure I parse these. ugh.
Right now they have the sequencing core names.
Get started on the pred model using the 16S data for now.
Get sequencing depth of the samples after quality control.
I need to get the whole meta genome sequences from the core after they run it through.
Change the name of the repo to conform to Schloss lab standards.
Hi there,
This is a semi-automated message from a fellow bioinformatician. Through a GitHub search, I found that the following source files make use of BLAST's -max_target_seqs
parameter:
Based on the recently published report, Misunderstood parameter of NCBI BLAST impacts the correctness of bioinformatics workflows, there is a strong chance that this parameter is misused in your repository.
If the use of this parameter was intentional, please feel free to ignore and close this issue but I would highly recommend to add a comment to your source code to notify others about this use case. If this is a duplicate issue, please accept my apologies for the redundancy as this simple automation is not smart enough to identify such issues.
Thank you!

The original bacterial metagenome prep did not work, which I think might have been due to a faulty kit. In addition to getting a replacement kit from Illumina, we are going to re-prepare this library using a new kit.
This is a rerun of the first kit that charlie prepped.
Pool the metagenome library samples.
I realized I don't have the sample information officially recorded in my master SQL sequencing database, so I need to go back and get that taken care of.
After the Quant-IT is done, we can calculate the volumes required to pool the samples. Once this is done we can submit the library.
Quantify the DNA for all of the samples in the virome metagenome library (second library that Charlie prepped) using the Quant-IT system.
Samples need to be run in duplicate to account for potential variation in the system.
Once this is done we can pool the samples and ship them off for sequencing.
Mothur server is down right now so I have to wait for it to be up before I can start this.
1: 24-sample NexteraXT library kit
1: 96-sample NexteraXT library kit
This is a pretty vague issue, but essentially I have the data up on Axiom so now I just have to go through with the main analysis workflow.
I should be able to follow the standard Mothur SOP.
Add simple mean and std error bar graphs of contamination levels to compare to previous studies. Simple as that.
The bacterial sample IDs need to be fixed to match up with my standard notation so that they can be easily merged with the viral and metagenomic samples.
yes, that.
I need to download the virome sequences from the core facility.
Need concoct to run with:
module load python/2.7.10
module load concoct/0.4.0
It looks like the impact of sequencing depth on the model performance might be fairly significant. To get at this, I would like to run some curves plotting model performance vs sequencing depth. I suspect that might be important here.
Get those ORFs clustered into OPFs.
Permission issues are preventing me from doing this now.
CONCOCT time.
Extracts ORFs from the contigs using Prodigal.
This run needs a mapping file which I can get from my SQL database.
Time for cutadapt
.
Use megahit to assemble contigs from the individual samples.
Get the number of sequences that map to the open reading frames.
I think that using the Diamond local aligner will be the best bet.
It seemed like there was something wrong with the first NexteraXT kit that Charlie used (for the whole metagenome prep). We need to contact Illumina and get them to replace that kit since they ain't cheap.
Charlie is going to be running the BioAnalyzer trace on the library after he fished the library prep itself.
There seem to be some problems with the alignments for making relative abundance tables.
Alpha diversity is done, but I still need to do beta diversity.
Quantify the DNA for the metagenome library prep using the Quant-IT plate quantification protocol.
I need to fix the rarefaction going into the random forest model. Plain and simple.
