FMRIB: pulse removal error

[arnodelorme]

Hi folks,

I've been working on EEG (during concurrent fMRI scanning) preprocessing, and trying to use eeglab FMRIB to remove pulse artifacts. I want to compare which method works best for my data, and I have no problem to apply all the rest 'artifact template info methods' except the 'Optimal Basis Set'. After qrs detection suceeded, I set PCA# to 3. It looks like the subtraction has been completed, as I received 'Pulse artifact subtraction in progress...Please wait!....25% ....50% ....75% ....100%', and then the eeglab shoots an error window showing '.... error in function fmrib_pas() at line 373: Error using-==>minus Matrix dimensions must agree...'. Notice that this didn't happen in three other methods.

Tested on EEGLAB v6.03b, test dataset(after epoching, EPI removal, downsampling, and qrs detection) attached.

Please let me know what you think. Thanks!

Lei
