Module symcurve::curve::matrix

This module contains some constants/matrices for curvature calculation.

Structs

• MatrixLookupError

Constants

• ROLL_ACTIVE
  The simple version fo the ROLL matrix is used to calculate the roll angle in three nucleotides of DNA.
• ROLL_SIMPLE
  The “activated” version of the ROLL matrix is used to calculate the roll angle in three nucleotides of DNA. This matrix differs from the simple matrix in that the angle values represent a more activated state of the nucleosomes bound to the DNA.
• TILT
  The TILT matrix is not really used in the current implementation, but is included here for completeness. The values are all 0.0 for all combinations of nucleotide triplets.
• TRIPLET_SIZE
  The number of nucleotides in a triplet, which is also the number of dimensions in the nucleotide matrices used for triplet -> value lookup.
• TWIST
  The TWIST matrix is used to calculate the twist angle in three nucleotides of DNA. The values are all 0.598647428 for all combinations of nucleotide triplets.

Type Aliases

• NucMatrix
  A type alias for a 3D matrix sized 4x4x4 of f64 values. The first dimension is the first nucleotide in a triplet, the second dimension is the second nucleotide in a triplet, and the third dimension is the third nucleotide in a triplet.
