<p>Nothing seems to be wrong in the slice presented in the
screenshot.</p>
<p>Maybe the best would be to look at the image generated from the
difference between the reference image and the image reconstructed
by your system, and check where do the differences come from.<br>

<div>Thank you for the information on the output image files.
I finally managed to open the files. <br>

I am working on Linux and the compiler used is "gcc version
4.7.2 (Debian 4.7.2-5)". I am pasting below a screen shot of
my image obtained. <br>
</div>
Also, this is the only benchmark, I have tried. <br>

<p>Hi Kajal,</p>
<p>Both reference and output images are saved in
interfile. You should be able to open it with any image
editor supporting this format. The .img file is a .raw
image of 112x112x109 voxels of 2.0x2.0x2.027 mm.<br>
</p>
<p>Regarding your results, several users with recent
compilers experienced similar issues with the benchmark.
The difference values weren't as high as in your results
though. Could you tell us what is your computer
hardware/OS ? And what is your compiler ? Is there any
artifact in the generated image ?<br>
<br>
Did you try the other benchmarks as well ?</p>
<p>Best regards,</p>
<p>Thibaut</p>

<div>Hello everyone, <br>

I am running a benchmark
"run_benchmark_pet_histogram.<wbr>sh", downloaded
from the Castor site. It generates two files,
"benchmark_pet_histogram_<wbr>challenger_it2.hdr"
and "benchmark_pet_histogram_<wbr>challenger_it2.img"
and it compares the files generated with the
reference files. I am copying the results below.
Can anyone please explain me how can I open the
two files generated and why the results of the
benchmark PET are not overlapping with the
reference files.<br>

Check benchmark results (compare reconstructed
image with the reference one)<br>

Double check all what you have
done first. Then email the mailing list.<br>
