v1.0.0 -- Stable now, only minor updates for CRAN once more

This is version 1.0.0, as we now consider this library pretty stable and feature complete.

The last few releases did not change anything or add new stuff, they were all just implementing minor doc changes requested by CRAN in their checks. Despite the jump in version number, there any no user facing changes compared to the last few releases. And thus of course no breaking changes.

v0.1.18 -- Minor updates for CRAN

v0.1.18

• Change some minor docstring issues in internal functions (requested by CRAN team)

Mostly CRAN fixes

Version 0.1.17

• Introduce 'default_label_name' parameter to read.fs.annot, better doc string for the same function.
• Add function fs.surface.to.tmesh3d to transform an fs.surface mesh datastructure into an RGL tmesh datastructure. This method does not require rgl.
• Replace all 'donttest' in examples with 'dontrun' so CRAN does not run them.

Small fixes and improvements, support Palm output files

Version 0.1.16

• Add experimental support for reading and writing Brainvoyager SMP files in format versions 4 and 5
• Add and export vertexdists.to.point function
• Allow MGH reading function to work with broken MGH files that contain no valid RAS header values but still claim so by setting the ras_valid flag in the header to 1. Allows to work with files written by palm.
• Add some new example usage scripts in the GitHub repository
• Fix bug #25
• Add 2 extra params to read.fs.surface.asc to make it more flexible

CRAN maintenance and some new helper functions

Version 0.1.15

• disable all unit tests that require downloaded data on CRAN
• add Euclidean distance util functions for surface vertices, like vertexdists.to.point and closest.vert.to.point
• add doapply.transform.mtx function (it's just matrix multiplication with some input checks that are annoying to repeat)

DTI track format support: TCK and TRK

This release adds support for 2 different Diffusion Tensor Imaging file formats:

• the MRtrix TCK format (in function read.dti.tck) and
• the trk format used by the Diffusion Toolkit and TrackVis in (function read.dti.trk).

I would have waited longer, but a release was needed for technical reasons related to CRAN.

The Nifti Release

Version 0.1.13

• support reading and writing Wavefront object files with non-standard vertex colors
• support reading NIFTI v1 files with FreeSurfer hack through our own, new NIFTI v1 reader. See read.nifti1.header() and read.nifti1.data() functions.
• support reading NIFTI v2 files through our own, new NIFTI v2 reader. See read.nifti2.header() and read.nifti2.data() functions.
• support writing NIFTI v1 files, see write.nifti1() and ni1header.for.data() functions.
• support writing NIFTI v2 files, see write.nifti2() and ni2header.for.data() functions.
• add function to check whether a file is in NIFTI v1 or NIFTI v2 format, see nifti.file.version() function.
• the read.fs.morph() function can now handle morphometry data files in NIFTI v1 format, including files with the FreeSurfer hack.
• the read.fs.morph() function can now handle morphometry data files in NIFTI v2 format.

More mesh formats, Brainvoyager support, transforms

Version 0.1.12

• add support for reading meshes in GEO format
• add support for reading meshes in TRI format (also known as ICO mesh format)
• add support for reading meshes in OFF format, the Object File Format
• add support for reading meshes in OBJ format, the Wavefront object format
• add support for writing FreeSurfer patch files in the ASCII format version
• add support for reading and writing meshes in Brainvoyager SRF format
• add support for reading and writing morphometry data maps in Brainvoyager SMP format
• add many unit tests and test files, use covr
• deprecate (imo) useless parameter 'empty_label_name' to read.fs.annot. using it will show a deprecation notice. (Please open issue if you feel you need it.)
• add experimental support for CIFTI v2 morphometry data files (.dscalar.nii), based on the 'cifti' package by J. Muschelli
• add support for reading transformation matrices from files in LTA and register.dat formats

Transforms, more mesh formats and better GIFTI support

Version 0.1.11

• export readable.files function
• support reading and writing meshes in mz3 format
• support writing PLY2 ASCII mesh format
• support reading mesh in BYU format
• support automatic conversion of quadrangular BYU meshes to triangular upon import
• add support for reading GIFTI format labels
• add support for reading GIFTI format annotations
• add support for writing GIFTI format labels
• add support for writing GIFTI format annotations
• export rotate2D and flip2D to namespace
• add support for reading transformation matrices from xfm files: read.fs.transform
• rename all optional data functions: replace optional_data with opt_data in function names to prevent clash with fsbrain names

NIFTI, GIFTI, mesh exports!

Version 0.1.10

• read.fs.label improvement: do not increment indices for volume labels, better print support for them
• support exporting surface meshes in Stanford triangle format (.ply)
• support reading surface meshes in Stanford triangle format (.ply)
• support exporting surface meshes in Wavefront object format (.obj)
• support exporting surface meshes in Object File Format (.off)
• support reading surface meshes in PLY format, including Blender exports with vertex colors and normals
• add general GIFTI writer (requires xml2)

• add read.fs.volume() function that support MGH, MGZ and NIFTI formats
• add experimental support for reading NIFTI volumes as fs.volume instances (via oro.nifti package), including header computation
