filter parameters

[balanca]

Hy,
I'm begining to use brainstorm, and as I was trying to change the filter apply to one of my dataset, I recieve this message in the "MATLAB" command window:


??? Reference to non-existent field 'F'.

Error in ==> dataplot_cb at 3898
new_waves = data.Measures.F{1}; % CBB - only one dataset here.

??? Error while evaluating uicontrol Callback.



I just wanted to change the default filters (high-pass 0Hz and low-pass 20Hz)to a high-pass frequency of 1Hz and a low-pass frequency of 150Hz.

Could you help me.....

thanks a lot, Baptiste balanca (EMI342 lyon, France).

Hi,

this should be feasible indeed. the error message indicates the dataset might not have loaded properly.

first, make sure your data are loaded by just clicking on 'Plot' in the DataViewer window. You should get the default butterfly plot of all channels and all time instants.

if they don't show up, it means you need to load a dataset in the dataviewer. DataManager > Right click over a data file > Select 'Load'

If the plot runs fine, try again to alter the filter parameters.

let me know how it goes.
