[MSNoise] stack problem in version 1.6

Dear All, I have just installed msnoise versions 1.6, in the configuration I set hpc to Y. After computing of cross-correlation, I use the command "msnoise new_jobs CC:STACK", which make stack job in the dashboard, but when I use the command "msnoise stack -r" it doesn't compute reference stack! I will be grateful, if you help me. regards, Navid
