ieegio 0.0.9

• Fixed CRAN check issues
• Added volume and surface related functions as MCP tools (can be loaded via package ravepipeline and ellmer)

ieegio 0.0.8

• Added new_space and as_ieegio_transform to define coordinate spaces and chain transforms
• Added io_read_ants_transform to read ANTs affine and displacement field transforms
• Added io_read_flirt_transform to read FSL FLIRT affine transforms
• Added volume_to_surface and surface_to_surface for mapping data between volumes and surfaces
• Fixed point transform ambiguity when chaining transforms with different interpretations
• Improved plot.ieegio_volume intensity windowing using percentile-based display range (2-98 percentiles), following conventions from FSLeyes, AFNI, MRIcroGL, and SPM
• Auto-detection for CT vs MRI data: excludes zeros by default but includes them when lower percentile is below -500 (indicating CT with -1024 background)
• Statistical overlay detection: applies symmetric range for z-score-like data
• Values outside display range are now clamped to boundary colors instead of rendering as transparent

ieegio 0.0.7

• Added as_nifti_header as a workaround when RNifti is missing (not installed or running in WebAssembly)
• Added automatic checks when pushing commits the repository to Github

ieegio 0.0.6

• Added write_edf to save signals as continuous EDF format
• Added YBA atlas (690 segments) to example data
• Improved HDF5 checking error messages

ieegio 0.0.5

• Added LazyFST class
• Fixed a bug where gzipped is ignored in io_write_nii.array
• LazyH5 fall back to alternatives when HDF5 is not supported in wasm
• Plotting surfaces use r3js by default
• Fixed BrainVision annotation bugs
• Supported writing to STL format (to support importing to BrainLab)
• Added supports to read streamlines data (trk, tck, tt, vtk)
• Writing to freesurfer surfaces also appends orientation information at the end.

ieegio 0.0.4

• Added merge support for both volume and surface objects; for surface objects, users can choose whether to merge the objects in model or world space
• Added dependency ravetools to help speed up sample volumes using C++
• Fixed missing transform issue in writing to GIfTI format
• Fixed write_surface not working when writing to FreeSurfer measurement (curvature) format
• Fixed a typo that caused setting volume data resulting in errors
• as_ieegio_surface does not require vertices

ieegio 0.0.3

• Cleaned h5py loader
• mat_to_quaternion always returns non-negative w now
• Added generics dim and length to volume object
• Fixed annotation issues in EDF format
• Time selection is double-sided using greater equal and less equal signs
• Added more sample data
• Supports colored (RGB[A]) formats
• Fixed color intensity when cal_min and cal_max is set
• Using r3js for visualizing surfaces
• Added resample_volume to sample images (currently only nearest neighbor)
• Added burn_volume to burn contacts (positions given in the image native RAS coordinate) with any given colors
• Fixed io_h5_names returning wrong names when using with h5py
• Exported internal class LazyH5 for down-stream packages
• Added as_ieegio_volume and as_ieegio_surface to enclose volume or surface data
• Added a flag to disable using Python

ieegio 0.0.2

• Added h5py as an alternative back-end support
• Fixed a bug where images are not loaded correctly due to image format being ignored
• Fixed Torig (index to tkr coordinate transform) issue
• Fixed a global variable issue
• Fixed a bug where file name is not respected

ieegio 0.0.1

• Initial CRAN submission.
