[Eeglablist] error while trying to import EGI/Philips Mat-file

[Eriksen, Jeff :LGS Neurodiagnostics]

Hello,

I exported a 256 channel EEG file using Net Station 4.5 to 'Matlab individual array' format and tried to import it into EEGlab 2019_1.
I got this error:

Pop_editset() error" cannot read .mat file 'path\name.mat'
Error occurred in function pop_editset() at line 445

Here is the output of the command window:

pop_editset(): raw data file 'D:\Research\LRI project\EEG 2019_1220\Session 2019_1220_1522.mat' found

The Mat-file has this content:

Session_2019_1220_1522mff, 257x693272 double
samplingRate, 1000
Impedances_0, 257x1 double
DIN_1, 4x630 cell

It appears the file was found OK, but could not be opened. Please advise on troubleshooting.
