Error in graph visualization

Bugs

Hi Brainstorm team,

I am trying to display as graph the connectivity on sensors(coherence), but I encountered an error: although I have set the threshold to the minimum value, not all edges are shown. For example, as seen in the image

, the C3xFp2 connection is not shown, although it is above threshold.

Thank you in advance,
Matteo

I could not reproduce this case where the threshold slider does not get updated correctly in the Display tab.

Could you please share this file, together with the corresponding channel file?

  • To reach a file: right-click on the file > File > Show in file explorer
  • Zip the ptimefreq_connectn_...mat and channel.mat file together
  • Upload the zip file somewhere
  • Post the download link here

Thanks

Thanks for your answer. Here's the link you asked for https://drive.google.com/file/d/1HFqyz-hlTmIf-qeFzRFLzIFX2-O5jYTA/view?usp=sharing

Thank you for the example data, I could reproduce and understand the behavior of the graph with your data.
There was a fixed maximum distance accepted between two nodes, and the distance C3-Fp2 was above this threshold.
I don't know why this test was here, I simply removed it: Bugfix: Graph viz: Removed arbitrary max distance threshold · brainstorm-tools/brainstorm3@7a0f99c · GitHub

The connection is now displayed:

Update Brainstorm to get this fix.

Any idea why this test was here?
Is there any chance I broke something?
