I can use the root output and with C code split this into .txt files which I am then planning on using IDL to convert to interfile. However, I am struggling to do the same with SPECT data. I can output data from different rotation angles but I believe I am going wrong because of the x,y,z coordinates of the heads changing for each projection.<o:p class=""></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Can anyone tell me if interrogating the root files is the correct approach or if I should be using ascii files?
