BioStructures - v4.5.0

• chiangle and chiangles are added to calculate the sidechain dihedral angles in protein residues.

BioStructures - v4.0.0

The package is made considerably more lightweight by moving a number of dependencies to extensions. This should make it easier for other packages to build on top of BioStructures.jl. Some types and functions are also renamed to avoid clashes, and a convenient string selection syntax is introduced.

Breaking changes

• PDB, PDBXML, MMCIF and MMTF are renamed to PDBFormat, PDBXMLFormat, MMCIFFormat and MMTFFormat respectively to avoid clashing with module names. read(fp, PDB) should be replaced with read(fp, PDBFormat), for example.
• ProteinStructure is renamed to MolecularStructure since it is not limited to representing protein structures.
• x, y, z, x!, y! and z! are no longer exported as they are common variable names. They are still available as BioStructures.x etc.
• Importing BioSequences.jl is now required to use LongAA.
• Importing BioSequences.jl and BioAlignments.jl is now required to use pairalign, superimpose!, rmsd/displacements with the superimpose option or Transformation on structural elements.
• Importing MMTF.jl is now required to use MMTFDict or writemmtf.
• Importing DSSPjll.jl is now required to use rundssp!, rundssp or the `rundsspoption withread/retrievepdb`.
• Importing STRIDEjll.jl is now required to use runstride!, runstride or the `runstrideoption withread/retrievepdb`.

Non-breaking changes

• Support for Julia versions before 1.9 is dropped.
• A string selection syntax is introduced, allowing selections such as collectatoms(struc, sel"name CA and resnumber <= 5").
• The selectors sidechainselector, proteinselector, acidicresselector, aliphaticresselector, aromaticresselector, basicresselector, chargedresselector, neutralresselector, hydrophobicresselector, polarresselector and nonpolarresselector are added.
• PDB parsing in certain situations is now much faster.

- Julia
Published by jgreener64 almost 2 years ago

BioStructures - v3.0.0

• On Julia 1.9 and later the DataFrame and MetaGraph constructors are moved to package extensions in order to reduce the number of dependencies. Calling using DataFrames and using Graphs, MetaGraphs respectively is now required to access these functions.
• The file formats PDB, PDBXML, MMCIF and MMTF are no longer subtypes of BioCore.IO.FileFormat, allowing BioCore.jl to be removed as a dependency.

- Julia
Published by jgreener64 about 4 years ago

BioStructures - v1.1.0

• Switch from using LightGraphs.jl to using Graphs.jl.

- Julia
Published by jgreener64 about 4 years ago

BioStructures - v1.0.0

• The ordering when sorting residues in a chain is changed from standard/hetero residue then residue number then insertion code to residue number then insertion code then standard/hetero residue. This makes in-chain hetero residues appear in the correct place in written PDB files.
• Support for Julia versions before 1.3 is dropped.

• Fix documentation build.

- Julia

BioStructures - v0.9.0

• A reader and writer are added for the MMTF file format, building on top of MMTF.jl. The interface is the same as for PDB and mmCIF files, with files either being read into the standard hierarchical structure or a MMTFDict. Gzipped files are supported. PDB, mmCIF and MMTF files can be interconverted.
• The expand_disordered flag is added to collectatoms, collectresidues, countatoms, countresidues, coordarray, writepdb, writemmcif, writemmtf and DataFrame. It determines whether disordered atoms and residues are expanded to include all entries. By default it is false except for the output functions, i.e. the last four above, where it is true by default.
• The pdbextension dictionary is changed to remove leading dots in the values.
• Improved file writing of empty elements.
• Examples are split off into a separate section in the documentation.
• A benchmark suite is added to track performance.

- Julia

BioStructures - v0.8.0

• Superimposition of structural elements is supported using the Kabsch algorithm. New functions are superimpose!, Transformation, applytransform! and applytransform.
• rmsd and displacements carry out superimposition by default, with the relevant keyword arguments available. Setting superimpose to false prevents this. rmsdatoms and dispatoms respectively determine which atoms to calculate the property for.
• The trivial allselector, which selects all atoms or residues, is added.
• The backbone oxygen "O" is added to backboneatomnames.
• Compatible bounds of package dependencies are added to Project.toml.

- Julia
Published by jgreener64 about 6 years ago

BioStructures - v0.7.0

• MetaGraph from MetaGraphs.jl is extended to create graphs of contacting elements in a molecular structure, giving access to all the graph analysis tools in LightGraphs.jl.
• DataFrame from DataFrames.jl is extended to allow creation of data frames from lists of atoms or residues.
• pairalign from BioAlignments.jl is extended to produce pairwise alignments from structural elements.
• AminoAcidSequence now takes any element type and has the gaps keyword argument.
• Documentation example of interoperability with NearestNeighbors.jl.
• Parametric types used more extensively internally.

- Julia

BioStructures - v0.6.0

• collectatoms, collectresidues, collectchains and collectmodels no longer run sort before returning the final list. The user can run an explicit sort themselves if desired. This change makes the functions faster and allows preservation of the element order.
• Speed up residue iteration.
• Documentation improvements.

- Julia

BioStructures - v0.5.1

• Fix MMCIFDict to always contain a Dict{String, Vector{String}} rather than a Dict{String, Union{String, Vector{String}}}, which includes making the "data_" tag a Vector{String}.
• More functions documented and documentation bugfixes.

- Julia
Published by jgreener64 over 6 years ago

BioStructures - v0.5.0

• The mmCIF reader now returns Array{String,1} for dictionary values even when there is only a single component. This improves consistency.
• Documentation expanded with references to Bio3DView.jl and an extra example.
• Replace REQUIRE with Project.toml.
• Bugfix when reading truncated MODEL line in a PDB file.

BioStructures - v0.3.0

• Code is now compatible with Julia v0.7 and v1.0. Support for earlier Julia versions is dropped.
• downloadpdb can now be given a function as the first argument, in which case the function is run with the downloaded filepath(s) as an argument and the file(s) are deleted afterwards.
• Improved function docstrings.

- Julia
Published by jgreener64 over 7 years ago

BioStructures - v0.2.0

• A reader and writer is added for the mmCIF format, which has been the standard PDB archive format since 2014. mmCIF files can either be read into a hierarchical structure object or directly in as a dictionary. PDB and mmCIF files can be interconverted.
• chainid now returns a String instead of a Char. This allows multi-character chain IDs. This also changes chainids, chain and chains. Chains can be accessed by string (e.g. struc["A"]), but can still be accessed by character for single chain IDs (e.g. struc['A']).
• show now returns a single line statement for objects across the module, in line with Julia conventions.
