[Eeglablist] Error message on

[Cedric Cannard]

It's definitely not the plugin because I use it on data with 256 Hz sample rate all the time.
It's because you don't have Matlab signal processing toolbox!

Not sure what the code does in this case, sorry. Maybe Arno, Makoto, or Christian can help?

I also verified the code in [GitHub](https://urldefense.com/v3/__https://github.com/sccn/clean_rawdata/blob/master/asr_calibrate.m*L146__;Iw!!Mih3wA!D81QmjB8wDdWqxjn_BRli5l0fbgTnBbBx7N5sGELJaPt1tvkERW90FBKKtFS_si5nfstbM6i5A-puwEQIq5xAlZhGg$  ), which has a case for 256 Hz. My best bet is that there's some issue with the toolbox license.

Either check the box in clean_rawdata (top of the window), or Tools > filter > type 1 in the lower edge box.

If you would like to use the default spectral filter please try to resample to one of the supported rates (110, 128, 200, 256, 300, 500, 512) or get the appropriate toobox license (you can also disable the spectral weighting feature or supply your own precalculated IIR filter coefficients).,
