gate_main.m issue #24

Closed June-phy closed 3 years ago

June-phy commented 3 years ago

Hi, When I run gate_main.m on Mac, the error pop up as below:

Error using save
Cannot create 'Cylindrical_PET_example_lor_pixel_count_128x128x63_sino_200x168x703.mat'
because '/Users/shanqianxue/Library/Application Support/MathWorks/MATLAB
Add-Ons/Toolboxes/OMEGA - Open-mat-files/ MATLAB emission tomography
software/mat-files' does not exist.

Error in lor_pixel_count_prepass (line 455)
                    save(file_string,'lor','-v7.3')

Error in precompute_data (line 46)
    lor_pixel_count_prepass(options);

Error in gate_main (line 1639)
   precompute_data(options);

Because there is a space before the file name MATLAB emission tomography software. But I didn't find the way to correct it in inlor_pixel_count_prepass.m. How can I change the save path?

This is indeed a bug when using the toolbox-version. For a quick workaround, simply replace line 100 in lor_pixel_count_prepass.m with folder = [folder(1:end-6), 'mat-files/'];

This bug is not limited to only this file, but others as well (same fix works there). These will be fixed in the next release.

The current master branch now contains the same fix as outlined above.
