Hello,

When I use both .ecg and .resp files, PhysIO returns an error for the .resp file:

Error using tapas_physio_filter_respiratory (line 137)
Usage: y=filtfilt(b,a,x)

In the exmaple files of PhysIO, I see that .resp file is used with .puls file, and .ecg file is used separately. So, is it not possible to use .resp and .ecg file (without .puls) to generate one regressor file?

Thanks in davance for your help.
