preprocessing question

[Floris de Lange]

Dear Fieldtrippers,

I get an error message in my first attempt to preprocess my first
dataset, so I'm probably having a true rookie problem here. If anyone
can point me to what might be wrong, that would be really nice however.
I get the following error message, while trying to remove artifacts from
my dataset:

identifying artifact-epochs
??? Error using ==> .*
Matrix dimensions must agree.

Error in ==> /home/common/matlab/fieldtrip/artifact_feedback.m
(convolve_suprathreshold)
On line 91  ==> datind = round(real(ifft(fftdat.*fftkrn,fftsmp)));

Error in ==> /home/common/matlab/fieldtrip/artifact_feedback.m

On line 229  ==>   eval(sprintf('[cfg, %s] = artifact_%s(cfg);',

Error in ==> /home/common/matlab/fieldtrip/preprocessing.m
On line 242  ==> [cfg] = rejectartifact(cfg);

Error in ==> /home/action/flodlan/MIVI-MEG/20050201/preproc_taco.m
On line 38  ==> Taco_EF_stimlocked = preprocessing(cfg);  % puts the
preprocessed data in data-structure

Just for completeness, I attached the preproc_taco.m and trials_extract.m.

Many thanks for your help,

Cheers,
Floris
