Detailed Description

Interface to read/write ANC files.

A ANC file contains analog channels data stored in ASCII format. Two generation of ANC file is known:

Generation 1 uses the analog resolution to scale the data;
Generation 2 uses the gains to scale the data. The use of the generation 2 (by default) creates file with a smaller size. You can use the method GetFileGeneration() and SetFileGeneration() to extract or set the the generation file respectively.

The ANC file format is created by Motion Analysis Corp.

Warning: The force platforms contained in this file format seem to be only force platforms of type II.; Moreover, Due to the file format, it is impossible to detect the correct scale for the force platforms' channels. Then, it is supposed, that the gain is 4000 and the excitation voltage is 10V. Plus, the scale factor is set as the opposite of the result to compute reactive forces.
