I have bit of an issue with Tracks 3 and 4, which seem to indicate that the metagenomic samples and its accompanying cytokine data are time varying. However, looking through the dataset, I cannot find any timestamps or something to indicate its time-sequence nature.
You need to merge 3 tabular files to see it
Yeah. I missed the date column on the cytokine data. I guess its date -> Sample_ID -> Subject_ID
Samples that have time stamps associated with them are in the cytokine data frame in the last column.
Note that when a sample is taken, up to 4 samples from the four different locations are taken at the same time AND a sample of blood is taken. The cytokine data is pulled from the blood data.
I hope this helps.
Thank you :)
