Converting AVL IFile data to MATLAB
catool can be used to convert raw combustion data in AVL IFile format for later analysis in The MathWorks' MATLAB.

The following configuration file will load an AVL IFile (avl_ifile.001) and output a MATLAB file (avl_ifile.mat).

catool can perform the relative to absolute pressure correction using the polytropic indices and crank angle range specified in the AVL IFile. To do this uncomment the three lines (channel-offset, analyse and run-analysis).
