Decimator problem
Posted: Tue Feb 09, 2010 10:01 am
Hi,
I try to use the Decimator executable to reduce size of files; because I have memory problems with EEGLab! However, when I decimate a dbf 2056Hz file to 1024Hz or less, the trigger channel is damaged, some trigger numbers are changed and sometimes new triggers appear! I looks like the Decimator 'decimate' the trigger channel like a normal signal channel recreating and consequently destroying the pulse square signal!
Any idea? I do something wrong?
My triggers are very short (1-5ms) square pulses send with the parallel port!
Thanks
