HMP2Data
October 31, 2024
Abstract
HMP2Data is a Bioconductor package providing the data of the integrative Human Microbiome Project (iHMP), also known as the second phase of HMP project (HMP2). It contains 16S rRNA sequencing data from three longitudinal studies, 1) MOMS-PI, pregnancy and preterm birth; 2) IBD, gut disease onset, inflammatory bowel disease; and 3) T2D, onset of type 2 diabetes and respiratory viral infection. Where available, other data is also provided, such as cytokine measures. Raw data files were downloaded from the HMP Data Analysis and Coordination Center. Processed data is provided as matrices, SummarizedExperiment, MultiAssayExperiment, and phyloseq class objects.

2.3 MultiAssayExperiment
We can construct a MultiAssayExperiment that will contain 16S and cytokine data for the common samples. Use the momspiMultiAssay function.
momspiMA <- momspiMultiAssay()
momspiMA
#> A MultiAssayExperiment object of 2 listed
#> experiments with user-defined names and respective classes.
#> Containing an ExperimentList class object of length 2:
#> [1] 16S: matrix with 7665 rows and 9107 columns
#> [2] cytokines: matrix with 29 rows and 1396 columns
#> Functionality:
#> experiments() - obtain the ExperimentList instance
#> colData() - the primary/phenotype DataFrame
#> sampleMap() - the sample coordination DataFrame
#> `$`, `[`, `[[` - extract colData columns, subset, or experiment
#> *Format() - convert into a long or wide DataFrame
#> assays() - convert ExperimentList to a SimpleList of matrices
#> exportClass() - save data to flat files2.3.1 Subsetting the MultiAssayExperiment object
The 16S rRNA data can be extracted from the MultiAssayExperiment object as follows.
rRNA <- momspiMA[[1L]]Or the cytokines data like so.
cyto <- momspiMA[[2L]]The sample data can be accessed with the colData command.
colData(momspiMA) %>% head()

5.1 Frequency Table Generation
The sample-level annotation data contianed in HMP2Data can be summarized using the table_two function. First, we need to make a list of the phyloseq and SummarizedExperiment objects which can then be entered into the table_two() table generating function.
list("MOMS-PI 16S" = momspi16S_phyloseq, "MOMS-PI Cytokines" = momspiCyto, "IBD 16S" = IBD, "T2D 16S" = T2D) %>% table_two()| N | % | N | % | N | % | N | % | |

We can also create a table of the breakdown of samples by visit number quantile.
list("MOMS-PI 16S" = momspi16S_phyloseq, "MOMS-PI Cytokines" = momspiCyto, "IBD 16S" = IBD, "T2D 16S" = T2D) %>% visit_table()| N | % | N | % | N | % | N | % | |

The patient-level characteristics can be summarized using the patient_table() function.

5.2 Visits Histograms
Here we plot histograms of the number of samples at each visit for the data MOMS-PI 16S data. Note that there are 196 samples at visit numbers over 20.
# set up ggplots
p1 <- ggplot(momspi16S_samp, aes(x = visit_number)) +
geom_histogram(bins = 20, color = "#00BFC4", fill = "lightblue") +
xlim(c(0,20)) + xlab("Visit number") + ylab("Count")
# theme(panel.background = element_blank(), panel.grid = element_blank())
p1
We can plot the histogram of the number of samples at each visit for all studies. Note that the X-axis is capped at count of 40 for better visualization.
# make data.frame for plotting
plot_visits <- data.frame(study = c(rep("MOMS-PI Cytokines", nrow(momspiCyto_samp)),
rep("IBD 16S", nrow(IBD16S_samp)),
rep("T2D 16S", nrow(T2D16S_samp))),
visits = c(momspiCyto_samp$visit_number,
IBD16S_samp$visit_number,
T2D16S_samp$visit_number))
p2 <- ggplot(plot_visits, aes(x = visits, fill = study)) +
geom_histogram(position = "dodge", alpha = 0.7, bins = 30, color = "#00BFC4") + xlim(c(0, 40)) +
theme(legend.position = c(0.8, 0.8)) +
xlab("Visit number") + ylab("Count")
p2
Note that there are 677 samples at visit numbers over 40.
5.3 UpsetR plots

# plot
upset(T2D_upset, order.by = 'freq', matrix.color = "blue", text.scale = 2)
6 Exporting Data to CSV Format
To our knowledge, R and Bioconductor provide the most and best methods for the analysis of microbiome data. However, we realize they are not the only analysis environments and wish to provide methods to export the data from HMP16SData to CSV format.
6.1 Preparing the data
For SummarizedExperiment objects, we will need to separate the data and metadata first before exportation. First, make a data.frame for participant data.
momspi_cytokines_participants <- colData(momspiCyto)

momspi16s_data <- as.matrix(otu_table(momspi16S_phyloseq))Finally, the taxonomy table can be extracted.
momspi16s_taxa <- tax_table(momspi16S_phyloseq) %>% as.data.frame()6.2 Save data as CSV
The data can be saved as .csv files as follows.
