GUI Bug in the Latest Brainstorm Update (19-Aug-2026)

Hi,

After updating to the latest BST version, I have come across the following bug:

When trying to get the source space PSD using the Power Spectrum Density (Welch) process, opening the “PSD options” by clicking the “Edit…” button, the new GUI (the one with a text area for the frequency bands) in unresponsive, as the “OK” button does not respond. When closing the secondary GUI (clicking x), the primary pipeline editor GUI does not allow executing:

“Error: Please check " PSD options" option in the process: "Power spectrum density (Welch)" before running the pipeline.”

Any help is appreciated.

Hello @pseifi,

Apologies for that bug, it was introduced on updating the way Brainstorm deals with dialog windows. Please re-update your Brainstorm instance, it will keep the same data (19-Aug-2026), but the TimeFrequency dialog will return to its previous behaviour.

Yes, it is working fine now. Thank you for fixing the bug. Regards, -PS
