The dataset recorded the open eyes activity. I've applied a filter (1-100Hz) and made the Avg excluding EOG and ECG. then run ICA and when I try to reject component by map this is the the result.

I'd like to see the bit of code where you try to call pwelch, including information about the input arguments. If you're doing it through a GUI, use the debugger to step through to find the bit of code. Also, tell me the output when you type

which pwelch
