How to remove specific regions from aseg_3d

[guilhermepovala]

Hello,

I'm using ggseg3d but I would like to remove from the 3D plot some specific regions, like Cerebellum, Brain-Stem, Ventricle...
How can I do that? I don't want to color these regions differently, but remove them completely from the plot.

Hi!

Sure!

I actually though I had made an entry on this in the vignettes, so I'll make sure to add one in the next realease.

library(ggseg3d)
library(dplyr)
library(tidyr)

# vector of labels
labs <- c("Left-Lateral-Ventricle",
          "Left-Inf-Lat-Vent",
          "Left-Cerebellum-Cortex",
          "Left-Pallidum ")

aseg_filt <- aseg_3d |> 
  unnest(ggseg_3d) |> 
  filter(
    # Of you 'dont want the ones in the vector
    !label %in% labs
  ) |> 
  as_ggseg3d_atlas()

ggseg3d(atlas = aseg_filt)

aseg_filt_rev <- aseg_3d |> 
  unnest(ggseg_3d) |> 
  filter(
    # Of you 'dont want the ones in the vector
    label %in% labs
  ) |> 
  as_ggseg3d_atlas()

ggseg3d(atlas = aseg_filt_rev)
