mia-2deval-transformquantity - Evaluate derivative of a transformation


mia-2deval-transformquantity -i <in-file> -o <out-file> -t <transformation> [options]


mia-2deval-transformquantity Get derivative a transformation obtained by using image
registration for any given positions in 2D. The position data is given in CSV format:
id;time;x;y;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=2 #number of dimensions of the data
components=7 #number of components per element
component_description=vector2,scalar,matrix2x2 #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 #grid size of the transformation
endian=low #endianess of binary data (low|big) }

This example header has to be interpreted like follows: two-dimensional data, each entry
consists of 7 values the values etry consists of a 2D vector, a scalar, and a 2x2 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 1000x1000 pixels and the binary
data is stored in low endian format.


-i --in-file=(input, required); string
input point set, if this parameter is given a sparse evaluation of the
quantity will be done, otherwise the quantity is evalutated for each grid
point of the transformation range.

-o --out-file=(output, required); string
output strains file, for a format description see above.

-t --transformation=(input, required); io
transformation of which the quantity will be evaluated. For supported file
types see PLUGINS:2dtransform/io

-q --quantity=strain
Specify the quantity to be evaluated at the given points
derivative ‐ Evaluate the transformation derivative at the given points
strain ‐ Evaluate the strain tensor at the given points

Help & Info
-V --verbose=warning
verbosity of output, print messages of given level and higher priorities.
Supported priorities starting at lowest level are:
info ‐ Low level messages
trace ‐ Function call trace
fail ‐ Report test failures
warning ‐ Warnings
error ‐ Report errors
debug ‐ Debug output
message ‐ Normal messages
fatal ‐ Report only fatal errors
