Hi everyone,

I downloaded some ephys data from the Allen CTD, and I am using it by referring to the cell id (i.e.: specimen\_id in the documentation) as follow:

```auto
cell_id = int(579462433)
my_Cell_data = ctc.get_ephys_data(cell_id)
index_range = my_Cell_data.get_sweep(int(sweep_id))["index_range"]
sampling_rate = my_Cell_data.get_sweep(int(sweep_id))["sampling_rate"]
...

```

However, I would like to know if it is possible to know the mouse\_id from which this cell has been recorded from?  
In general, is there a way for me to know the information of the animal directly by providing the cell\_id?

Thank you for any help you can provide!

Best regards,

Julien Ballbé

Hi Julien,

You could use the [CellTypesApi](https://allensdk.readthedocs.io/en/latest/allensdk.api.queries.cell_types_api.html#allensdk.api.queries.cell_types_api.CellTypesApi) instead of the CellTypesCache to get that information.

For example:

```python
from allensdk.core.cell_types_cache import CellTypesApi

cta = CellTypesApi()
cta.get_cell(579462433)

```

which produces

```auto
{'cell_reporter_status': 'positive',
 'csl__normalized_depth': None,
 'csl__x': 9590.88840160779,
 'csl__y': 1846.28433696584,
 'csl__z': 3291.2638202753,
 'donor__age': '',
 'donor__disease_state': '',
 'donor__id': 578231840,
 ... # many more things
}

```

Also, there is a [CSV of the metadata in the Cell Types Database](https://celltypes.brain-map.org/cell_types_specimen_details.csv) linked to from the [Cell Feature Search page](https://celltypes.brain-map.org/data) - that file has `donor __id` and `donor__ name` columns, too, in case it’s easier for you to get the information that way.
