I have preprocessed my seismic wave, but there are a few warnings like these.
**1.UserWarning: Input sampling rate of stage 4 is inconsistent with the previous stages’ output sampling rate**
**2.WARNING (norm\_resp): computed and reported sensitivities differ by more than 5 percent. \*\*
\*\* Execution continuing.**
**3.InternalMSEEDWarning: GE\_MORC\_\_BHZ\_D: Warning: Number of blockettes in fixed header (2) does not match the number parsed (1)**
I think it is related to remove response and I use the command:
trace.remove\_response(inventory=inventory,pre\_filt = [0.001, 0.005, 50, 55],output=“VEL”)
I use channel in BHZ. Is the warning related to metadata？
Any hint will be fine!

1. and 2. seem to be some problems in the metadata while 3. would be a problem in the waveform data.
