EEG/SEEG scrolling and others

Hello Francois,

I started using BST after a long break, and it's fantastic. Several issues that I could not get around when trying to look at the SEEG.

  1. While > and >> are ok, >>> is not working, nothing happens, the page does not advance (and this after zooming on x axis to make sure I have several pages to go through; I then tried other keyboard shortcuts shown in the tutorials, such as
  • F3/Shift+F3 : Jump to the next/previous epoch or page (10% overlap between 2 pages)
  • F4/Shift+F4 : Jump to the next/previous half-page (50% overlap)
  • F6/Shift+F6 : Jump to the next/previous page with no overlap (0% overlap)

and they do not work either; some mouse ones do not as well.
What can be done, I assume my shortcuts are not set correctly, unless there is a bug?

  1. When scrolling with > or >>, when the bar gets to the end of the screen, the SEEG does not move with it, so the bar simply disappears, is this expected? The only way that I can advance the page now if pressing/holding the mouse wheel down and moving the mouse.

  2. In clinical recordings, the absolute recording date/time shows up for orientation and issues of synchronization, can we make it appear inside the display instead of relative time?

  3. Can one use the amplitude scale be set to standard units (mm, cm), irrespective of pixel data, say 7 microV/mm, instead of the "difference between two horizontal lines? I tried the same numbers with what we use clinically, but the sensitivities do not match; comparing the scale legend by eyeballing is tough.

Sorry for the traffic, but want to make it work well, thank you again. Octavian

Welcome back!
Maybe you could have a look at the news page and the updated tutorials to get an idea of the nea features of the software:

Scrolling in time is only available for continuous recordings. Make sure you are using the menu "Review raw file" and not "Import MEG/EEG":

When scrolling with > or >>, when the bar gets to the end of the screen, the SEEG does not move with it, so the bar simply disappears, is this expected?

The viewer is not designed to work much in a "zoomed" display. If you want to review a continuous file, use the menu "Review"

In clinical recordings, the absolute recording date/time shows up for orientation and issues of synchronization, can we make it appear inside the display instead of relative time?

It depends whether it's available in the file format you used.
For EDF and Nihon Kohden, if you right-click on the figure, you should see the corresponding wall-clock time.

Great, thank you!
