All NaN in mALFF

Submitted by Patrizia on

Dear Dr. Chao-Gan Yan,

 
I use DPARSFA software to perform my resting state analyses.
However, this time there is something strange: many mALFF images are entirely NaN (see example attached). 
Nevertheless all the ALFF, fALFF and mfALFF included signal and the weighted images seem to be fine.
 
May you explain me why this happen and how I can fix this error?
 
Thank you very much in advance,
