[Gate-users] Using XCAT-attenuation information in simulation

[AliAsghar Parach]

Dear Linnmann
you can convert the float data of your attenuation phantom into integer(by
using of .log file created while you construct your xcat phantom) and then
convert your file to uint16 and etc.

hope this help you.
