    <p>I have two datasets listing the average voltage outputs of two assemblies of neural networks at times t, that look something like this:</p> <pre><code>A = [-80.0, -80.0, -80.0, -80.0, -80.0, -80.0, -79.58, -79.55, -79.08, -78.95, -78.77, -78.45,-77.75, -77.18, -77.08, -77.18, -77.16, -76.6, -76.34, -76.35] B = [-80.0, -80.0, -80.0, -80.0, -80.0, -80.0, -78.74, -78.65, -78.08, -77.75, -77.31, -76.55, -75.55, -75.18, -75.34, -75.32, -75.43, -74.94, -74.7, -74.68] </code></pre> <p>When two neural assemblies are "in phase" to a reasonable extent, that means that they are interrelated. What I want to do is calculate the phase difference between A and B, preferably over the whole time of the simulation. Since two assemblies are unlikely to be totally in phase, I want to compare that phase difference to a certain threshold.</p> <p>These are inharmonic oscillators and I don't know their functions, only these values, so I have no idea how to determine the phase or the respective phase difference.</p> <p>I am doing this project in Python, using numpy and scipy (the two assemblies are numpy arrays).</p> <p>Any suggestions would be greatly appreciated!</p> <p><strong>EDIT: Added plots</strong></p> <p><a href="http://server1.brainstormit.nl/vb-sync-XReport.txt" rel="nofollow noreferrer">Example datafile for assembly 1</a></p> <p><a href="http://server1.brainstormit.nl/vb-sync-YReport.txt" rel="nofollow noreferrer">Example datafile for assembly 2</a></p> <p>Here is a plot of what the two datasets look like: <img src="https://i.stack.imgur.com/l3fbP.png" alt="Plot of two neural assemblies overlapping"> <img src="https://i.stack.imgur.com/mrjIh.png" alt="Plot of two neural assemblies seperate"></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
