Due to the bandwidth of our connection
QUBE looks considerably less fluid as it is in reality
ESPRIT QUBEPlease note

What is QUBE ?
• For post processing of data sets acquired by analytical scanningelectron microscopy
• For 3D reconstruction of tomographic dataacquired by surface techniques such as EBSD and EDS
• Integrative analysis of 3D data sets
• Interactive processing pipeline
• Simultaneous operation on multiple data set types

ESPRIT QUBEData files
7
Import 2D data sets:
• EBSD: Bruker format (.bcf) and other common formats (e.g .ctf)
• EDS: Bruker (.bcf)
• SEM Images: common bitmap formats (.bmp, .gif, .png, .jpg etc.)
3D project:
• All 3 data types are saved into a single 3D project (.qml)
• .vti export, (.hdf5 planned)
• Export of images, lists and intermediate results
ESPRIT QUBEViewing & navigation
8
Viewing:
• “Real time” voxel rendering (wysiwyg)
• Extensive color codes for EBSD, EDS and SEM images
• Semi transparency for scalar data fields(e.g. see only areas of high GND density)
Navigation by:
• Tomography (slicing, cut outs etc.)
• Voxel-wise: 3D cursor
• Grain-wise: “grain neighborhood”
ESPRIT QUBEFilters and geometry
9
Geometry editing:
• Affects EBSD, EDS and SEM data sets
• Cropping and slice deletion
• Slice re-alignment (based on EBSD data)
Data filtering:
• Currently for EBSD data only
• Linear filters (Gaussian, box)
• Non linear filters (Kuwahara, median)
• Despeckling (outliers)
ESPRIT QUBEAnalytical tools
10
Analysis of EBSD data:
• Grain segmentation (extensive grain list)
• Local average disorientation (LAD)
• Approximated GND density (based on LAD)
• Schmid factor
• Subsets
Voxel subset options:
• Predefined subsets: textures, LAD, grain metrics, grain texture, grain neighborhood
• Save and copy customized subsets within project
• Export/import subsets
• Apply subsets across data sets
(e.g. EBSD grain subset in EDS data set)

Data compatibility:
• Signals whether derived child data is still in sync with parent data.
History:
• Data operations are logged sequentially in project file.
Reversibility:
• Data changing operations can be undone.
ESPRIT QUBEData monitoring
12
Multiple data sets:
• Multiple: EBSD and/or EDS and/or SEM images
• Operate on multiple data sets simultaneously(currently limited to the data editing operations)
• Apply subsets across data sets (e.g. apply EBSD subset on EDS data set)
• Viewing 2 data sets simultaneously by color blending(e.g. blend EBSD with SE data set)

Summary
• Tool for post-acquisition analysis of tomographic data sets
• Multiple data sets: EBSD, EDS, SEM images
• Wysiwyg
• Extensive subset possibilities
• Data monitoring
• Ever growing functionality
