make_ggseg3d_2_2_ggseg: error in evaluating the argument 'x' in selecting a method for function 'cellStats': subscript out of bounds

Hi Dr. Mowinckel,

I've tried to convert the 3D ICBM atlas to 2D using the code below. I've run into a few errors I'm not sure how to debug (but am hoping you have a better idea of what they mean).

Just to make sure the example works, I also ran test <- make_ggseg3d_2_ggseg() which uses the dk by default - this seems to work & I was able to plot the results just fine.

I'd appreciate any insight,

Best wishes,

John

Hi!

Sorry for the late response. The ICBM is a subcortical atlas, and as such cannot be created into 2d from the 3d-atlas. Only the cortical atlases can do this (because they are inflated). To create the ICBM in 2d, you will need to use the make_volumetric_ggseg()

Here is some information about using that function. You will need the original ICBM atlas file to make this work.
