Location

sampling sites from the release coordinates

No sample coordinates in this release

The study reports no latitude or longitude, and its metadata carries no lat_lon text field either, so no map or place-name hierarchy can be drawn. Every other panel is computed from the count table and the sample metadata.

ampliconflow branches off at step 6, Sequencing

this release

ampliconflow starts here: 1,517,927 reads from 48 runs, QC to 99.1% 16S identity and 91.8% above Q30, primers trimmed, dada2 1.38.0 to 5,310 ASVs, taxonomy against a SINTAX reference, then the release (CC-BY-4.0).

Steps 1 to 6 are how the sequences were obtained, from the study's own archive metadata. Step 7 is what the authors report doing with the sequences in the linked paper. ampliconflow starts at the deposited reads rather than repeating the wet lab.

Taxonomy assigned with SILVA 138.2 (SINTAX).

Downstream QC and analysis

Eleven modules, computed from the released count table, the sample metadata and the per-run QC reports. Each panel states its own n and the test it used; a module that cannot run on this release is shown as a flagged gap rather than an empty frame.

Rarefaction

2k 5k 10k 20k 50k 100k 504 0

Expected richness when 48 samples are subsampled to a common depth, resampled 31 draws. Median 101 features observed at full depth.

Depth against richness

log depth
550 0 reads per sample, log scale

One point per sample. Correlation of log reads with observed features is 0.668, so the depth floor is doing most of the work of deciding how many features a sample shows.

Bray-Curtis dissimilarity

48 x 48, darker is closer

Sample order is the release order, 48 labels, and the matrix itself ships as beta_distance.tsv beside the analysis.

Phylogenetic diversity

Not available for this release: no Newick tree beside the table; run the tree stage, then re-run analyze. The legacy analysis computed Faith's PD when the container carried a tree, and this one reports the absence instead of an empty column.

Batch-bias audit

states against

adjusted Rand n/a p = n/a

not enough levels to test

permutations. Every sample here carries both MiSeq and MiniSeq runs, so the batch variable used is the one with two levels, here .

Variance partitioning

mean R2 per feature, CLR

Joint R2 n/a, so the metadata explains a modest slice of the feature variation, and the two variables are not independent of one another.

Effect size

No two-level comparison available.

Taxa against all samples

with

features tested, 0 survive the correction at q ≤ 0.05

Nothing survives. The smallest q is n/a, which is the honest answer for a study whose samples are spread across three years with two to thirteen samples per year.

    The contamination class separates the communities beyond the spread within each class (PERMANOVA) with no evidence that the spread itself differs (PERMDISP). Distance decay runs over n/a to n/a km.

      Phylogenetic and signal analyses need a tree

      no Newick tree beside the table; run the tree stage, then re-run analyze. The tree stage aligns the ASVs with MAFFT and builds with FastTree, both detected as external tools; neither is installed on the machine this page was built on, so Faith's PD, UniFrac, Pagel's lambda and Blomberg's K are left flagged rather than guessed.
