thermodynamic_nn_params: Thermodynamic Tables for Nucleic Acid Hybridization

In TmCalculator: Genome-Wide Nucleic Acid Melting Temperature Profiling and Multi-Omics Integration

Thermodynamic Tables for Nucleic Acid Hybridization

Description

A comprehensive collection of thermodynamic parameters used for calculating melting temperatures of nucleic acid duplexes. The dataset includes parameters for DNA/DNA, RNA/RNA, RNA/DNA and 2'-O-methylRNA/RNA hybridizations, plus parameters for mismatches, dangling ends, internal / bulge loops, GU wobble, CNG repeats, inosine, hydroxyadenine, azobenzene and locked nucleic acids (LNA).

Usage

thermodynamic_nn_params

Format

A named list of two-column matrices with colnames = c("left", "right") (left = \Delta H, right = \Delta S). Rownames are dinucleotide step keys such as "AT/TA", mismatch / dangling-end keys, or feature-specific keys (e.g. "CAG_4" for the (CAG)4 CNG entry).

To add the numeric values for any placeholder table, construct a matrix with two columns (\Delta H kcal/mol, \Delta S cal/(mol*K)) and the dinucleotide-step rownames described above, then assign it:

thermodynamic_nn_params$DNA_CNG_Broda_2005 <- new_table

Details

Coverage mirrors the rmelting (Bioconductor) vignette sections 4.2.1 - 4.4. Tables whose numeric values are not yet ported from primary literature are included in the list as NULL placeholders so that tm_nn can still dispatch on the table name; the corresponding contribution is silently skipped after a one-time package-startup notice.
