Thank you very much for reply. This is the MATLAB code I used to extract dose information:
________________________________
workpath1 = 'C:\workdir\weeklyreport\20140302_DoseSimulation\dosedata\Doserecord-Dose.img';
fid = fopen(workpath1,'rb');
dose1 = fread(fid,[128,128],'float');
figure,imagesc(dose1);
title('thorax dose distribution');
________________________________
Thank you!
Best regards
Wei

Dear Gate user,


I have calculated the dose map for a voxelized phantom which was generated with a CT image. The image was transfered into GATE as .h33 and .i33 format. The dose maps was written in standard hdr/img format. But when I read the dose map in MATLAB, there are a lot of NaN in the body area and the dose value for air is fine. Did anyone know how to solve this problem? I will appreciate any feedback.

Thank you very much!
