Bandpass filtering

 Hi,

I'm trying to use the rest_bandpass function in your toolkit, but I can't get it to read my data. Specifically, I get the error message below. If I try to use the GUI, I get an error dialog saying "There is no data or non-data files in this directory".

I get the same message for different datatsets. I have made sure that only the volumes and not other files are in that directory. I can use the image files with no problems using other analysis packages.

Thanks for your help,

Alex
