@gero-studios gero-studios released this 21 Oct 22:48

NVAP 0.1.5 fixes microglia structures disappearing from the colored post-segmentation All view.

Fixed

  • The colored All view now preserves the full above-threshold green signal, including voxels that segmentation has not assigned to an accepted cell. Detected cells keep their individual tints; unassigned signal stays green.
  • Unassigned signal is display-only and is not counted as an extra cell or added to per-cell analysis.
  • Large-volume rendering preserves thin foreground branches during downsampling instead of skipping them between sampled positions.
  • Colored surfaces use the same opacity as the original intensity view.

Verification

  • On the saved cortex reference, the old view omitted 511,935 of 1,608,598 above-threshold voxels. The corrected All view preserves the complete threshold mask, with zero missing voxels in both dense and memory-saving cache modes.
  • Threshold and slice trimming remain active. Source intensities, cell labels, and analysis measurements are unchanged.

Windows downloads

  • NVAP-0.1.5-windows-cpu.exe — standalone Windows x64 CPU build.
  • NVAP-0.1.5-windows-directml.exe — standalone Windows x64 build with DirectML GPU support and CPU fallback.
  • SHA256SUMS.txt — checksums for both executables.

Download the appropriate executable and run it. To view the corrected segmented result, run Segmentation and choose Cell: All in the Microglia Viewer with View one microglia enabled.
