Missing Meshes

[dsmiddendorf]

I have seen that meshes for some brain regions are not available.

For instance...

mesh_list <- map("MOBgr", ccf_2017_mesh)

results in ...

Error in map(): ℹ In index: 1. Caused by error in unz(): ! cannot open the connection Run rlang::last_error() to see where the error occurred. Warning message: In unz(zip_file, vb_file, open = "rb") : cannot locate file 'vb_220.num' in zip file 'C:/Users/danmi/AppData/Local/R/win-library/4.2/cocoframer/extdata/ccf_2017_meshes.zip'

I think, in this example, the mesh for the "Main olfactory bulb, glomerular layer" is missing and can, therefore, not be accessed.
Is there any solution to add or make regions that are not easily retrievable available?

Thank you!
