README

This file describes the content of the different files including in this repository to reproduce results from [1] and some of its supplementary results.

Input files

• 20151016_Functions_remainder.csv

  Functions measured in [2]. The relevant quantities used in [1] are labelled with "7", and include:

  • Community: Id of the sample
  • Replicate
  • Plate
  • mgCO2.7: CO2 measured along 7 days of experiment
  • CPM7: Cell counts at the end of the experiment
  • pgRPC.7: CO2 per cell
  • ATP7: ATP measured (nM)
  • mG7: beta glucosidase (mM)
  • mN7: beta chitinase (mM)
  • mX7: xylosidase (mM)
  • mP7: phosphatase (mM)

• samples_metadata_time0.tsv

  • Samples: Id of the sample
  • Part.dates: Date of sampling
  • Part.GPS.PAM: Optimal sampling sites
  • Part.SparCC.PAM.t0: Optimal partition using SparCC
  • Part.SJD.PAM.t0: Optimal partition using Jensen-Shannon Divergence
  • Part.Dir.t0: Optimal partition using Dirichlet mixtures
  • Part.month: Month in which the community was sampled

• Dist_GPS-Haversine.dat

  Haversine (spatial) distances between samples

• corMat-SparCC_20151016_OTU_remainder.clean.samples.txt

  Matrix of correlations between samples computed with SparCC

• distMat_ShannonJensen_Samples_Time0.clean.dat

  Distance matrix computed with Jensen-Shannon divergence.

Supplementary results

• SEMmodels.zip

  Results for the Structural Equation Models analysed. The structure of the folders follows the one available at the repository of the project .

• TaxaSummaries.zip

  The file contains one folder for each community-class, with matrices in different formats (biom and txt) computing the relative abundances of the OTUs at different taxonomic levels (labelled L2 being the proxy for Phylum to L6, the proxy of species). These matrices can be visualized interactively opening with a web browser the files area_charts.html.
