MIQ-Win 1.3.0

• Added ITK MetaImage (.mha) support.
• Added experimental split-format support: Analyze/NIfTI pairs, MetaImage .mhd, and NRRD .nhdr, including first-volume loading for large uncompressed split-format datasets.
• Added voxel indices and optional header comments to metadata.
• Improved orientation reporting, including conflicting NIfTI qform metadata.

Fixes

• NRRD orientation: NRRD files are no longer assumed to be in RAS space. Orientation labels and the neurological/radiological view modes now apply only when the header has both an anatomical space and space directions. Otherwise the image is shown in stored order. Spaces ending in -time (such as right-anterior-superior-time) are now supported.
• Faster navigation through .gz files: when you move to another file while a compressed volume is still loading, the plugin now stops reading it right away instead of finishing the read first.

MIQ-Win v1.2.2

Fixes

• Fixed some masks (off center) not rendering correctly.
• Very small value ranges (e.g. ADC maps in SI units) now get proper contrast.
• 4-D .nii.gz files over 4 GB no longer get stuck on "loading...".
• If loading all volumes fails, the preview now says so instead of showing "loading..." forever.
• int64/uint64 images, such as label maps saved from NumPy, now open.
• MRtrix intensity scaling is now applied to MIF files.

Performance

• Moving to another file cancels the unfinished load of the previous one.
• MIF masks are detected about 25× faster.
• Settings are read only once per preview.

MIQ-Win 1.2.1

A bug-fix release that brings in the fixes from MIQ 1.5.1 for macOS.

Fixes

• Very small image values now show contrast. Images that store tiny numbers, such as ADC maps saved in SI units, used to come out as one or two flat shades of grey. They now show the full contrast range.
• Unusual voxel sizes display correctly. Files that give a voxel size of zero or an invalid value used to collapse to a thin line or a single dot. They now render at a sensible size. The metadata panel still shows the voxel size exactly as the file states it.
• Faster, more reliable NRRD loading. Some NRRD files, especially ones saved by 3D Slicer or ITK, could be read wrongly or load slowly. They now open correctly.
• NIfTI-2 files are labelled correctly. The metadata panel now shows "NIfTI-2" or "Compressed NIfTI-2" for these files instead of "NIfTI-1".

Segmentation coloring

• Smarter label-map detection: fewer misses, no miscolored intensity images.
• Rich parcellations now supported (Destrieux, wmparc, Schaefer/HCP-MMP).
• SegmentationColors = auto is now the default (new installs only, existing MIQ.settings.ini files keep grayscale until you change the key).

Formats

• MIF: support for the Bit datatype (bit-packed masks).

Robustness

• Hardened NIfTI/NIfTI-2, MGH, MIF and NRRD header parsing against malformed or out-of-range dimensions and offsets.
• A decode failure while scrolling no longer crashes QuickLook.
• Improved handling of NaN and Inf voxels.
• Fixed MIF anatomical orientation ignoring the transform: header, which could mislabel left/right on obliquely-transformed volumes.

New features:

• Segmentation coloring: Applies a color LUT when a label file is detected. For aseg/aparc label files, it uses canonical FreeSurfer colors.
• Inspect the voxel value at the crosshair position (in interactive mode)
• Performance improvement: Optimized rendering performance.

Fixes:

• Switched to significant digits instead of fixed decimals for displaying scaling.
