| extdata {CHNOSZ} | R Documentation |
The files in the subdirectories of extdata provide additional thermodynamic data and other data to support the examples in the package documentation and vignettes.
See thermo for a description of the files in extdata/OBIGT, which are used to generate the thermodynamic database.
Files in Berman contain thermodynamic data for minerals using the Berman formulation:
Ber88_1988.csv contains thermodynamic data for minerals taken from Berman (1988).
Other files with names like xxx_yyyy.csv contain thermodynamic data from other sources; xxx in the filename corresponds to the reference in thermo$OBIGT and yyyy gives the year of publication.
Berman uses these data for the calculation of thermodynamic properties at specified P and T, which are then available for use in subcrt.
If there are any duplicated mineral names in the files, only the most recent data are used, as determined by the year in the file name.
Following conventions used SUPCRT92 (see Helgeson et al., 1978), the names of sanidine and microcline were changed to K-feldspar,high and K-feldspar,low (by using the same names in all data files, loading the optional SUPCRT92 data file updates these minerals rather than makes new ones).
sympy.R is an R script that uses rSymPy to symbolically integrate Bermans's equations for heat capacity and volume to write experessions for enthalpy, entropy and Gibbs energy.
The testing directory contains data files based on Berman and Aranovich (1996). These are used to demonstrate the addition of data from a user-supplied file (see Berman).
Files in cpetc contain experimental and calculated thermodynamic and environmental data:
PM90.csv Heat capacities of four unfolded aqueous proteins taken from Privalov and Makhatadze, 1990. Temperature in °C is in the first column, and heat capacities of the proteins in J mol^{-1} K^{-1} in the remaining columns. See ionize.aa and the vignette anintro for examples that use this file.
RH95.csv Heat capacity data for iron taken from Robie and Hemingway, 1995. Temperature in Kelvin is in the first column, heat capacity in J K^{-1} mol^{-1} in the second. See subcrt for an example that uses this file.

bluered.txt Blue - light grey - red color palette, computed using colorspace::diverge_hcl(1000, c = 100, l = c(50, 90), power = 1). This is used by ZC.col.
AD03_Fig1?.csv Experimental data points digitized from Figure 1 of Akinfiev and Diamond, 2003, used in demo("AD").
TKSS14_Fig2.csv Experimental data points digitized from Figure 2 of Tutolo et al., 2014, used in demo("aluminum").
Mer75_Table4.csv Values of log(aK+/aH+) and log(aNa+/aH+) from Table 4 of Merino, 1975, used in demo("aluminum").
Files in protein contain protein sequences and amino acid compositions for proteins.
EF-Tu.aln consists of aligned sequences (394 amino acids) of elongation factor Tu (EF-Tu). The sequences correspond to those taken from UniProtKB for ECOLI (Escherichia coli), THETH (Thermus thermophilus) and THEMA (Thermotoga maritima), and reconstructed ancestral sequences taken from Gaucher et al., 2003 (maximum likelihood bacterial stem and mesophilic bacterial stem, and alternative bacterial stem). See read.fasta for an example that uses this file.
rubisco.fasta Sequences of Rubisco obtained from UniProt (see Dick, 2014). See the vignette anintro for an example that uses this file.
POLG.csv
Amino acid compositions of a few proteins used for some tests and examples.
These are various subunits of the Poliovirus type 1 polyprotein (POLG_POL1M in UniProt).
TBD+05.csv lists genes with transcriptomic expression changes in carbon limitation stress response experiments in yeast (Tai et al., 2005).
TBD+05_aa.csv has the amino acid compositions of proteins coded by those genes.
The last two files are used in demo{"rank.affinity"}.
Files in taxonomy contain taxonomic data files:
names.dmp and nodes.dmp are excerpts of NCBI taxonomy files (https://ftp.ncbi.nih.gov/pub/taxonomy/taxdump.tar.gz, accessed 2010-02-15). These files contain only the entries for Escherichia coli K-12, Saccharomyces cerevisiae, Homo sapiens, Pyrococcus furisosus and Methanocaldococcus jannaschii (taxids 83333, 4932, 9606, 186497, 243232) and the higher-ranking nodes (genus, family, etc.) in the respective lineages. See taxonomy for examples that use these files.
Files in adds contain additional thermodynamic data and group additivity definitions:
BZA10.csv contains supplementary thermodynamic data taken from Bazarkina et al. (2010). The data can be added to the database in the current session using add.OBIGT. See add.OBIGT for an example that uses this file.
OBIGT_check.csv contains the results of running check.OBIGT to check the internal consistency of entries in the default and optional datafiles.
RH98_Table15.csv Group stoichiometries for high molecular weight crystalline and liquid organic compounds taken from Table 15 of Richard and Helgeson, 1998. The first three columns have the compound name, formula and physical state (‘cr’ or ‘liq’). The remaining columns have the numbers of each group in the compound; the names of the groups (columns) correspond to species in thermo$OBIGT. The compound named ‘5a(H),14a(H)-cholestane’ in the paper has been changed to ‘5a(H),14b(H)-cholestane’ here to match the group stoichiometry given in the table. See RH2OBIGT for a function that uses this file.
SK95.csv contains thermodynamic data for alanate, glycinate, and their complexes with metals, taken from Amend and Helgeson (1997) and Shock and Koretsky (1995) as corrected in slop98.dat. These data are used in demo("copper") and demo("glycinate").
