3D positions of cells being displayed incorrectly

Nessuno ha ancora preso questa issue.

This [NeuroML file](https://github.com/OpenSourceBrain/NetPyNEShowcase/blob/master/NeuroML2/TwoCells/TwoCell.net.nml#L44) contains 2 cells, a basket cell on the left (at the origin) and a pyramidal cell on the right (at ``). The soma of the pyramidal cell should be below the basket cell as shown in this export of the cell from NML (use: `pynml -png TwoCell.net.nml`, see [here](https://docs.neuroml.org/Userdocs/VisualisingNeuroMLModels.html#view-the-3d-structure-of-your-model)):


However when this is imported into NetPyNE (e.g. by creating a workspace from https://v2.opensourcebrain.org/repositories/14 and importing the NML file above) the soma is above the basket cell (left below):


The correct position seems to be in netpyne's memory, as the right panel shows its own 3D view, with the yellow dot on the right for the pyramidal cell at the right locaion.

Also a json file exported from the neuroml version has the right location: https://github.com/OpenSourceBrain/NetPyNEShowcase/blob/master/NetPyNE/TwoCells/LEMS_TwoCell_netpyne_data.json#L29

Is it possibly the issue is to do with the `"ynorm": -2.0` linked above, as the y position looks like it is wrongly multiplied by -2?

Riproduci il problema creando un workspace dal repository collegato e importando NeuroML2/TwoCells/TwoCell.net.nml. Confronta le coordinate delle cellule visualizzate con l’esportazione NeuroML e NetPyNE/TwoCells/LEMS_TwoCell_netpyne_data.json, in particolare la posizione y e il valore ynorm della cellula piramidale. Il lavoro è completato quando la vista 3D importata posiziona costantemente il soma della cellula piramidale sotto la cellula a canestro, in modo coerente con i dati di origine.
