<p class=MsoPlainText><span lang=EN-GB>You have to be care with one thing: GATE
can’t read float data (32 bit)! So you'll need to convert your phantom file to
unsigned interger (16 bit) format (with IDL or MATLAB for instance).<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>Just do the data conversion and follow the
hoffman brain example inside the GATE distribution!!<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-GB>Careful: check you image conversion
before launch your simulation… If all scripts are well defined and you got the
message above, probably is because the conversion <span style='color:black'>wasn't
