EEGLAB version is 8.0.3.4.b

Win 7 Professional 64 bit

 

I am trying to filter and Processing continuous data with the Tools > Filter
the data > Basic FIR filter by entering "1" as the lower edge. 

eegfilt() - performing 1500-point highpass filtering.

eegfilt() - highpass transition band width is 0.2 Hz.

...................20..........

After reaching the last step (1643861:1865960) the filtering process breaks
up with the following error massage:

 

buffer invalid error

invalid input argument #1

 

The items of the continuous Data file are:

 

Channels per frame         30

Frames per epoch            1865960

Epochs                               1

Events                                3621

Sampling rate (Hz)           500

Epoch start (sec)              0.000

Epoch end (sec)                3731.918

Channel locations            Yes

Reference                          nose tip

ICA weights                       no

Data size (Mb)                  225.2

 

What's going wrong?

 

Thanks

Ralf
