EEGLAB version is

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.


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?
