[Eeglablist] AMICA error on 256 channels EEG

[liao ke]

Hi Hyeonseok:

Thank you for your reply!

I move AMICA into a Linux system and it works.

I also try to run command on Windows terminals and it doesn't go well. It
gives an error message like:
'The code execution cannot proceed because libiomp5md.dll was not found.
Reinstalling the program may fix this problem.'
Then I download the libiomp5md.dll file from Jason Palmer website and get a
new error this time:
'The ordinal 747 could not be located in the dynamic link library
C:\eeglab\eeglab2021.0\plugins\AMICA1.6.1\amica15mkl.exe'

So I decide to run AMICA on Linux for my data now. Thanks for your help.

Best,
Ke
