SYNOPSIS

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

DESCRIPTION

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.

OPTIONS

File-IO

-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

Parameters

-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
