[MSNoise] About s03compute_cc

[Sammarco, Carmelo]

thanks Thomas for this info.

1) yes.. 125 Hz
2) the configured cc_sampling_rate is 1 HZ

So what can you suggest me to run correctly the computations? What decimation factor and/or resample value I need to use?? May explain me in witch way I can understand what is the correct parameters?

Is it possible resolve the bug or ignore it to finish the computation?

thank you very much.

Hi Carmelo,

1/ It looks like you are using 125 Hz data, is that right ?
2/ What is the configured "cc_sampling_rate" value ? I suppose it's 1 Hz.

The first error is because you can't decimate by a factor of 5 to go
from 125 to 1Hz.
The second looks like an error in the resample method which gives back 2
samples less than expected, and it's a bug.
