Connectome Workbench (macOS Qt6) – Maps not displaying fully

[parham zargar2]

Hello,

I am running into a visualization issue in Connectome Workbench. Whenever I load surface or volume data (e.g., .surf.gii, .dscalar.nii), the map only appears partially within the viewer. It looks clipped or cut-off, and I cannot get the full brain/map to display.

Steps I have tried so far:

• View → Reset View (and the R shortcut).

• Switched Montage layout (Landscape, Single, Row, Column).

• Zoomed out and panned manually.

• Changed display mode between Surface, Volume, and Montage.

• Loaded different files (flatmaps, inflated, midthickness, dscalars). The files open without error messages but still do not render fully in the viewer.

• Confirmed files are intact and load fine on a different system.

Environment:

• OS: macOS [Sonoma 14.5]

• Workbench build: Connectome Workbench 2.0.1

• Data: HCP S1200 release (e.g., S1200.L/R.midthickness.32k_fs_LR.surf.gii, S1200.myelin.dscalar.nii)

Thank you very much for your help,
Parham

Hi Parham,

Try this:

 

• Go to wb_view menu
• Select Preferences
• On Preferences dialog, click the Displays tab
• Set “High DPI Mode” to Auto or On

 

Best, 

Jenn
