[Eeglablist] "inconsistent number of samples in trial 1" error in DIPFIT

[Makoto Miyakoshi]

Dear Nikola and Nikola,

It's great that solution was successfully shared and the problem solved!
If you don't mind, we would greatly appreciate if you could file the case
to EEGLAB bugzilla. https://sccn.ucsd.edu/bugzilla/enter_bug.cgi
