In bio3d: Biological Structure Analysis

Biological Structure Analysis

Description

Utilities for the analysis of protein structure and sequence data.

Details

Package:	bio3d
Type:	Package
Version:	2.4-5
Date:	2024-10-25
License:	GPL version 2 or newer
URL:	http://thegrantlab.org/bio3d/

Features include the ability to read and write structure (read.pdb, write.pdb, read.fasta.pdb), sequence (read.fasta, write.fasta) and dynamics trajectory data (read.dcd, read.ncdf, write.ncdf).

Perform sequence and structure database searches (blast.pdb, hmmer), atom summaries (summary.pdb), atom selection (atom.select), alignment (pdbaln, seqaln, mustang) superposition (rot.lsq, fit.xyz), pdbfit), rigid core identification (core.find, plot.core, fit.xyz), dynamic domain analysis (geostas), torsion/dihedral analysis (torsion.pdb, torsion.xyz), clustering (via hclust), principal component analysis (pca.xyz, pca.pdbs, pca.tor, plot.pca, plot.pca.loadings, mktrj.pca), dynamical cross-correlation analysis (dccm, plot.dccm) and correlation network analysis (cna, plot.cna, cnapath) of structure data.

Perform conservation analysis of sequence (seqaln, conserv, seqidentity, entropy, consensus) and structural (pdbaln, rmsd, rmsf, core.find) data.

Perform normal mode analysis (nma, build.hessian), ensemble normal mode analysis (nma.pdbs), mode comparison (rmsip) and (overlap), atomic fluctuation prediction (fluct.nma), cross-correlation analysis (dccm.nma), cross-correlation visualization (pymol.dccm), deformation analysis (deformation.nma), and mode visualization (pymol.modes, mktrj.nma).

In addition, various utility functions are provided to facilitate manipulation and analysis of biological sequence and structural data (e.g. get.pdb, get.seq, aa123, aa321, pdbseq, aln2html, atom.select, rot.lsq, fit.xyz, is.gap, gap.inspect, orient.pdb, pairwise, plot.bio3d, plot.nma, plot.blast, biounit, etc.).
