[Eeglablist] Out of memory when loading a CNT

[Christopher Wilke]

Hi Min-

Your problem is likely due to the manner in which the different
operating systems handle memory. With Matlab, the largest variable size
is determined by the largest contiguous block of free memory. Therefore,
even though your Windows machine has 2.5G RAM, the maximum variable size
Matlab is able to create and store could be much, much smaller,
particularly if you have several processes running in the background.

You can check the free contiguous blocks of memory at the Matlab prompt
by typing: system_dependent memstats

There is a helpful web tutorial dealing with large datasets in Matlab on
the Matlab Central File Exchange
(http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=9060&objectType=file#).

Hope this helps.

Best regards,

Chris

Hi experts,
My CNT file is less than 400M (32bit). When I used an iMAC with 1G RAM,
the CNT file could be imported successfully. However, when I used myPC
with 1G RAM, the loading was out of memory. So I changed to another PC
with 2.5G RAM, the same thing happened again. Thus, I am confused why a
PC with 2.5G RAM worked worse than an iMAC with only 1G RAM?
Thanks a lot to any help!
