files using ImageJ, however, I get a large file filled only with zero values in the matrix. In other words, all of matrix characteristics are as assigned in the Actors macro (size, dimensions etc.) but I cannot find any signals (positive values) anywhere.

<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica","sans-serif";color:black">My guess is that the code requires the geometry to be read in as an image with .hdr format and that the sphere created by the code itself is not adequate
when you use doseActor (?) I would appreciate your opinion in this area and whether you think there is an easier way of designing this simulation without having to create a sphere separately, converting it into Analyze format and then reading it into the code.
I am enclosing some of the relevant information with this e-mail. Thank you.<o:p></o:p></span></p>
