[Eeglablist] ICA: slow and then crash on one file

[Jeff Hanna]

Hello all,

I'm having trouble running ICA on one particular file; all the others seem 
to work fine. This file takes several orders of magnitude longer than the 
others (i.e. overnight), and ultimately crashes, claiming to be out of 
memory. The recordings are downsampled to 200hz, and being processed on a 
workstation with 8gb of RAM, so it's very unlikely that an actual RAM 
shortage is the problem. The recordings were done with 128 electrodes, with 
bad channels removed (*not* interpolated). Looking at the continuous data, 
nothing seems out of the ordinary. Does anyone have an intution of what may 
be wrong? I'm doing this on a 64-bit version of Matlab 7.8.
