[Eeglablist] FW: [EXTERNAL] JAVA exception while trying to import EGI/Philips MFF format file

[Eriksen, Jeff :LGS Neurodiagnostics]

Hi again,

No one responded to my email of Feb 7. Any EGI/Philips MFF file format users out there?
I am now using v3.0 of MFFMatlabIO, no improvement, same error.
Thanks,

-Jeff

Subject: [EXTERNAL] [Eeglablist] JAVA exception while trying to import EGI/Philips MFF format file

Hi,

I have not used EEGlab for several years. I am now using an older EGI NA200 system, 256 channels, running NetStation 4.3 to acquire data. I use another computer with NetStation 4.5 to convert the native files to MFF format. When I tried to import one of these using File:Import data:Using EEGLAB...:Import Philips .mff file, I get this message:

JAVA exception occurred
[4 lines of JAVA details] (cannot copy and paste this text) Error occurred in function mff_importevents() at line 62

And here is the command window output:

My JAVA heap is 2.013 MB.
Matlab is v9.6/R2019a.
EEGlab is v2019.1

Any suggestions on what I might do next to troubleshoot this problem?
