[Homer-users] problems with hmrBandpassfit on HOMer2

[Perdue, Katherine]

Hi Xiaopan,

Do you have another “butter” function in your path? Homer uses the one in the signal processing toolbox. If you use “which" you can see which one is being called like:

>> which butter
/Applications/MATLAB_R2013b.app/toolbox/signal/signal/butter.m

(I have version 2013b not 2014a)

If it is not calling the one in the signal processing toolbox you should edit your path so that the other butter function is not on it or the signal processing toolbox butter has precedence.

best,
Katherine

Dear all,

When I put the hmrBandpassfit in the process stream and ran it, it always showed the error like the picture I attached (I am using matlab2014a).

I tried several data files, but all the same. I just wondered that whether anyone met this problem before.

Thanks for any suggestions.

Xiaopan
