[Eeglablist] Help with Neuroscan and Analyzer files

[Arnaud Delorme]

Dear Elia,

I think the problem is both because of your Matlab version and also  
the fact that you are running out of memory. When Matlab crashes it is  
never EEGLAB fault, but I agree that this can be frustrating. Read the  
data, and save it using EEGLAB data format. Then restart Matlab and  
reload the data. This might ease slightly the memory burden.

We have a new version of EEGLAB that uses memory mapping so the file  
stays on disk. Unfortunately Matlab memory mapping implementation is  
not stable and Matlab crashes often when we use this option. We are  
trying to stabilize it using the SPM memory mapping implementation  
instead of the Matlab one (SPM implemented their own memory mapping  
routines within Matlab more than 10 years ago) but this might take time.

Best,

Arno
