data filtering in Fieldtrip

[Mikhail Zvyagintsev]

Dear Robert,
I have a question regarding filtering in Fieldtrip. I see, that in 
example routines you apply quite often 'butter' function. I got a 
feeling that this is rather a rude approach (I might be wrong). For 
example, I see that some important information could be lost using it. I 
am trying to use 'firpmord' function to generate parameters and then 
'firpm' for filter design. For filtration 'fltfilt' like you do. They 
all need Sgnal Processing Toolbox, therefore it should not be a 
limitaion. What is your opinion about filtering?
Thanks in advance,
Mikhail.
