Hello, I have continuous data in which there are no events in my EEG data, but after the process of filtering and cleaning I have some annotations called: ‘Bad\_muscle’. now I can not add these annotations as events. and I think it interrupts my visualization and time-frequency analysis.  
Thank you in advance.

- MNE version: 1.2.2
- operating system: Windows 10

```python
print(raw.annotations)
print(set(raw.annotations.duration))
print(set(raw.annotations.description))
print(raw.annotations.onset[0])

```

**The result of this cell is:**

```python

```

**In the next cell I run:**  
`mne.events_from_annotations(raw)`  
**and the result is the error:**  
`ValueError: Could not find any of the events you specified.`

By default, the annotations starting with `BAD` are ignored. Have a look at the `regexp` argument of `mne.events_from_annotations`.

Thank you for replying!  
As you said, I change my code to:  
`events, event_id = mne.events_from_annotations(raw, regexp = None)`  
and it worked. Is it ok to use?

Sounds good to me. None probably disables the filtering by name entirely. You could also just change the regex pattern to match `'BAD_muscle'` if that’s the event you want to capture.
