I'm getting an error when I reading ascii surface files from one tomography set produced in amira 2019.2, the error reads:

Input:
dfx<-read.hxsurf("myamirafile.surf")
Output:
Error in read.hxsurf("myamirafile.surf") :
Bad triangle number: 650952

I have a loop pulling in all datasets in a folder, but none from these sets reads. I've tested older sets, and they read in fine, so I'm a little worried about this. Any help is appreciated.

I've attached two surface files from two different tomographic EM projects, both give bad triangles error but different triangle number. The surface file comprises around a hundred small materials. I push the limits of amira's material number max in the field files.

I appreciate any help.
