Dear MNE users/developers,

I try to filter my data using 

mne_process_raw --lowpass 55 --highpass 5  --projoff …

As program output I got the following:

Filter :   5.000 ...   55.0 Hz   bins : 40 ... 450 of 4097 hpw : 3 lpw : 20
Highpass filter will work as specified.
filter :   0.000 ...   40.0 Hz   bins : 0 ... 327 of 4097 hpw : 3 lpw : 20
Highpass filter will work as specified.


Does it mean that program first filter 5-55 Hz and then uses the default 0-44 Hz filter?

If I use 
mne_process_raw  --filteroff --lowpass 55 --highpass 5  --projoff …
No filtration seems to happen.

Elena
