I am trying to access the Microns co registration data. I downloaded it from [here](https://bossdb-open-data.s3.amazonaws.com/iarpa_microns/minnie/functional_coregistration/func_unit_em_match_release.csv)

This csv contains data about 200 neurons only. Could you direct me to where I could get the complete set of data?

Hi, we just recently are completing a new version of the release with about 10K functionally coregistered neurons. Right now its available through the CAVEclient interface under a new datastack name ‘minnie65\_public\_v343’ we will work on updating the static copies available as CSV files over the next month.

See the instructions on MicronsBinder for setting up a CAVE account

Then in python

```auto
import caveclient
client=caveclient.CAVEclient('minnie65_public_v343')
df=client.materialize.query_table('functional_coreg', split_positions=True)
df.to_csv('functional_coregistration.csv')

```

Thank you very much! I was using the older datastack **minnie65\_public\_v117** on caveclient and did not know about the new one. How can I check for these updates myself?
