I have labeled a data set ner-d3, and now I want to modify some of the previous annotations, what should I do.  
I tried to use the following command, but I think this command is marked again on the basis of the previous one, rather than modified, so I don't know what to do, looking forward to your reply. Thanks

> python -m prodigy ner.correct ner-d3 ./model-best --label MD,GD,D  
> D,RD,PHON

hi @Zanejins!

Can you describe what you want to modify? Are you only correcting the labels?

Prodigy has a [helpful `dataset:` syntax](https://prodi.gy/docs/api-loaders#datasets) that may help.

> The `dataset:` syntax lets you specify an existing dataset as the input source. Prodigy will then load the annotations from the dataset and stream them in again. [Annotation interfaces](https://prodi.gy/docs/api-interfaces) respect pre-defined annotations and will pre-select them in the UI. This is useful if you want to re-annotate a dataset to correct it, or if you want to add new information with a different interface. The following command will stream in annotations from the dataset `ner_data` and save the resulting reannotated data in a new dataset `ner_data_new` :

```python
python -m prodigy ner.manual ner_data_new blank:en dataset:ner_data --label PERSON,ORG

```

So in your case, you could run something like:

```python
python -m prodigy ner.correct ner-d3-new ./model-best dataset:ner-d3 --label MD,GD,DD,RD,PHON

```
