Hello !
I am working on the aisynphys database and more specifically on adjusting the connectivities. I tried to run the connectivity\_adjustments notebook ([aisynphys/connectivity\_adjustments.ipynb at current-release · AllenInstitute/aisynphys · GitHub](https://github.com/AllenInstitute/aisynphys/blob/current-release/doc/connectivity_adjustments.ipynb)) but I get this error when I run the last cell :
```auto

raise ValueError(

```
I think the shape of adjusted\_connectivity is the issue, but what should I put instead?
Best,
Margaux

Hello Margaux, we are looking into this and will get back to you as soon as we can!

Hi again Margaux, I have not been able to reproduce this error. However I did encounter some other bugs in this notebook that have been fixed and pushed to the `current-release` branch that you linked to above. Perhaps you can try running a clean version of this notebook?
If that doesn’t help, can you post the output of `conda list` from your conda environment? I suspect your error may be due to a change in matplotlib version.

It helped, now it works !
Thanks !
