errors when slice timing

Dear all REST experts:

I use DPARSF to process the data acquired from different following times. The data from the first two following times were processed successfully without any errors and bugs. However, when processing data from later following times , the following processing problems about slice timing occurs. Can anybody help me or give me some suggestios? Thank you.

I would say restart matlab and re-run again.
