I receive the following errors when trying to run a spatial PCA with Infomax rotation on temporal PCA factors (using the data from the tutorial):
__________________________________________________________________________________
"Error: PCA was not successful. Binary ICA does not work if any part of the pathname (C:\Program Files\MATLAB\R2012a\bin) has a space in it."

When I tried just changing the EEGlab and working directory to have no spaces, I received the following error:

Warning: You have a binary ICA program installed. The file is called: ica_linux

Interestingly, the spatial PCA runs fine when selecting 0 factors to obtain a scree plot, but it fails when selecting to retain 5 factors. I'm running Windows, so I didn't think it would try to run ica with binica. What is the problem?
Thanks for your help.

Hmm, I've read the installation instructions in the tutorial several times, and I can't see where I've gone wrong. Here is what I've done:
1. Installed MATLAB
2. Created a folder for Matlab Programs within the MATLAB installation folder
3. Installed the latest EP Toolkit (and set paths in Matlab)
4. Installed the latest EEGLAB (and set paths in Matlab)
5. Installed the latest FieldTrip (and set paths in Matlab)
6. Deleted the external FieldTrip folder as part of EEGLAB, and deleted the external EEGLAB folder as part of FieldTrip
I chose to stay with runica and not install binica because binica does not appear to be available for Windows. I also did not install the gcc compiler because I don't plan to do dipole analysis. Finally, I did not install Satimage because it's not available for Windows. What am I missing?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
For some reason, the latest version of EEGlab comes set to use the linux version of binary ICA, which is why your run is crashing. You need to change this since you're not running linux. See the instructions on page 9. If you wish to disable the binary file (which I recommend) then set ICABINARY = ; See EEGlab documentation fore more information.
