Problems with Virtual Fiber Tracks for Connectivity Visualization

Hello,

I'm following the tutorial Virtual Fiber Tracks for Connectivity Visualization. It only mentions about displaying fibers for single subject.
But I want the average result of between-subject analysis, so I tried import fibers for "Default anatomy" in the anatomy view, and I saw the option "display fibers" when I right-clicked the connectivity results in the "group-analysis" file, but there is something wrong with the display of brain surface (just displaying a little part of the surface).

Is there anyone who can help me solve this problem?

Can you share a screenshot of the state of the Surface tab in the main Brainstorm window?


This is the screenshot. Is there anything wrong with the settings? @Raymundo.Cassani

I've tried modulating the settings in the Surface tab but it didn't works @Raymundo.Cassani

Thanks for sharing the details. It seems there is a problem with the registration of the fibers and the other anatomy files.

  1. Can you properly display the fibers in the Anatomy view, by double-clicking them?

  2. If the fibers are shown, display the cortex in the same figure.

    1. In the Surface tab, click on the Add a surface button
    2. Add Cortex
    3. Set transparency to ~80%
    4. Turn off Scouts display in the Scout tab

    Are the cortex and fibers well aligned?

  1. Which Default anatomy are you using?
  2. Which fibers file are you importing?

thank you for reply!
I tried the above step, but the cortex couldn't be displayed correctly after I added Cortex.
I think the default anatomy is ICBM152(I didn't import the default anatomy by myself. It displayed by itself)
And the fiber I added is the file(whole_brain_MNI_3k.trk) that I downloaded from official website

The screenshot is what I see now.(the scout function is unactivated now)

Besides, the projection template I used when dealing with source estimation is "Default anatomy--cortex_15002V"(following the tutorial)
@Raymundo.Cassani

Thank you for the screenshot.
The issue seems to be the default (in green) cortex cortex_15002V | keep, I'm not sure how this was created, but it is likely to be a subset of the entire cortex.

  1. Close all figures
  2. Right-click on the cortex cortex_15002V, and select Set as default cortex
    (Alternatively, you can double-click this cortex to make it the default)
  3. Try again to plot the fibers + cortex
