 A GATE example with GATE macros is available in exampleGATE-folder. Simply run the GATE macros as a GATE simulation (the GATE material database needs to be in the same folder as the macros) and then run the `gate_main_example.m` to load and reconstruct the data. By default, ASCII data is used for compatibility.

 Only cylindrical symmetric devices are supported inherently, for other types of machines the user has to input the detector coordinates.
 
 Attenuation correction can be applied only with attenuation images (e.g. CT images scaled to 511 keV).
 
 ECAT geometry is supported only with ASCII data. ROOT data might also work (untested).

 If you are experiencing crashes when using implementation 2, it might be caused by the graphics features of ArrayFire. In this case I recommend renaming/removing the libforge.so files from the ArrayFire library folder (e.g. `/opt/arrayfire/lib64/`). Alternatively you can install the no-gl AF:  
 http://arrayfire.s3.amazonaws.com/index.html (3.6.2 is the latest). Finally, you can also simply build AF from source, preferably without building Forge. This seems to apply only to Linux and affects both MATLAB and Octave.

 ROOT data import is unstable in MATLAB R2018b and earlier versions due to a library incompatibility between the Java virtual machine in MATLAB and ROOT. On Linux you will experience MATLAB crashes when importing ROOT data. There is a workaround for this by using MATLAB in the no Java mode (e.g `matlab -nojvm`), though you won't have any GUI or graphic features. MATLAB R2019a and up are unaffected.
 
 ROOT is not supported on Windows, though it should, theoretically, work if you use ROOT with 32-bit MATLAB, but this is untested.
 
 ### Octave
 
-Implementation 2 (ArrayFire matrix free OpenCL) is not supported on  Windows due to a compiler incompatability between MinGW and ArrayFire. As mentioned elsewhere, this can be fixed by building ArrayFire from source with MinGW.

 MAT-files that are over 2 GB are not supported by Octave and such large data sets cannot be saved in Octave at the moment.
