mia-3deval-transformquantity - Evaluate derivative of a transformation
mia-3deval-transformquantity -o <out-file> -t <transformation> [options]
mia-3deval-transformquantity Get derivative a
transformation obtained by by using image registration for any given
positions in 3D. The position data is given in CSV format:
id;time;x;y;z;reserved The output data will be stored in a binary file with
an ascii header describing the data. An example header is given below:
MIA tensorfield {
dim=3 #number of dimensions of the data
components=13 #number of components per element
component_description=vector3,scalar,matrix3x3 #interpretation of components
elements=20 #number of elements in file
interpretation=strain #interpretation of elements (strain|derivative)
style=sparse #storage style (sparse|grid)
repn=float32 #representation of values
size=1000 1000 200 #grid size of the transformation
endian=low #endianess of binary data (low|big) }
This example header has to be interpreted like follows: three-dimensional data, each entry consists of 13 values the values etry consists of a 3D vector, a scalar, and a 3x3 matrix (saved in row-major format).The data records represent strain tensors, and only a sparse set of points is given. The values are given as single floating point (32 bit). The original transformation field corresponds to images of 1000x1000x200 voxels and the binary data is stored in low endian format.
Derivative of the transformation change.v3df for each point given in input.csv are evaluated and written to output.s.
mia-3deval-transformquantity -i input.csv -o output.s --transformation change.v3df
