----------Description of files----------------
resulting DIC maps as tif stacks to be opened as stack with ImageJ (version 1.52n, Open Source software available at https://imagej.nih.gov/ij/download.html) or comparable programs (e.g. Avizo) suitable to display 3D image datasets
at first, stacks appear black --> adjust colorbar

file structure of image stacks:
DIC-maximum_shear_strain-field-0073x0073x0106
DIC-volumetric_strain-field-0073x0073x0106
DIC-xx_strain-field-0073x0073x0106

DIC: Digital Image Correlation
maximum shear strain field (in range 0 --> 0.1 in colorbar)
volumetric strain field (in range -0.1 --> 0.1 in colorbar)
xx/yx/yy/zx/zy/zz strain field: strain tensor components
0073x0073x0106: Image resolution

tsv file: relative displacements of each pixel. The displacement unit is pixel based on the pixel size of the X-Ray images (=13.5 µm).
NodeNumber: Node Number
Zpos: initial position on z axis
Ypos: initial position on y axis
Xpos: initial position on x axis
Zdisp: relative displacement in Z direction 
Ydisp: relative displacement in Y direction
Xdisp: relative displacement in X direction
Zrot/Yrot/Xrot: rotational component (not used here)
CC: Correlation Coefficient (0=no match, 1=perfect match)
Error: Error codes of used DIC software
