File Formats

open_iA supports several file formats. It reads:

• Raw images (uncompressed binary data) (any extension; automatically detected as such: *.pro, *.raw, *.rec, *.vol)
• MetaImage (*.mhd, *.mha)
• VG Studio Scenes (*.vgi)
• DICOM series (*.dcm)
• Olympus FluoView files (*.oif)
• AmiraMesh files (*.am) (only the uncompressed volume data format)
• Serial VTK Image data (*.vti)
• Several common image formats (*.bmp, *.jpg/*.jpeg, *.png, *.tiff/*.tif) (plus stacks of such images as volumes)
• Hierarchical Data Format v5 (HDF5) (*.hdf5, *.he5, *.h5)
• Matlab (*.mat) files (.mat file format version 7.3, which uses HDF5, see https://mathworks.com/help/matlab/import_export/mat-file-versions.html)
• STL files (Polygon data) (*.stl)

It writes:

• Volumes:
  • MetaImage, in its bundled .mha format, or the combination of a .mhd descriptor and a .raw file (the latter is a standard raw file, as can be read by most programs dealing with volumes, if additionally given the volume dimensions and spacing, as given in the .mhd descriptor file)
  • AmiraMesh files (only the uncompressed volume data format)
  • ITK HDF5 files
• Meshes:
  • STL files
